DMAX Owner Silences Naysayers

00:01 today is the day I’ve been trying to do this video for like two weeks but Towing out here to Salt Lake is not easy guys but if you don’t know I have a 2024 GMC Sierra 2500 has the Duramax Gen 2 l5p and I did these upgrades to it front and center is the hot side for the Boost tubes you can

00:21 kind of see the turbo inlet from here you can kind of see it there it is now you can’t really see it but yeah I did the inlet right there and this is the cold side right down there so we’re going to see last video I did I went up a steep grade 6% and I got to 75 mph where this

00:47 truck pretty much topped off at I’m wondering if with this extra air going into the engine will it help me to increase the speed now if it can be 75 mph I’ll be happy what I do know is this really helps in the mid-range now the Boost comes on a lot quicker so that should help as well so

01:11 what I’ll do is when we get to the 6% grade I’ll drop down to 50 m hour like I did last time and we’re going to send it so let’s go ahead and get set up get down the road and let’s see how this truck does I just had some technical difficulties with my camera I always forget when I

01:47 use my truck I have to disable all my Bluetooth functions everything because it just messes with my camera but we’re good now so I just reset the fueld economy all that good stuff and let me get over one more time so this truck I’ve said this in the past this is probably one of my favorite

02:07 trucks like I truly think out of every truck I’ve owned so far with the exception of the duly the dly was probably it’s in a different class because of what I did to it but this is my favorite stock truck 100% it is absolutely the greatest because it has a lot of the features that I’ve always

02:25 wanted I’ve always said this I always wanted a luxury off-road truck and GMC built it and this truck has all the nice features now the only negative thing about this truck is is not the greatest quality I’m going to be honest with you guys like I have not been happy with my GMC for Quality

02:44 like there have been some things I’ve gotten a lot of things to replace on this truck I’m going to do a video on it for my onee ownership of this truck but so far it’s been my favorite but it hasn’t been the best when it came down to just overall quality reliability has been great no issues

03:01 there um and you know I will say Jim has some Gremlins in there emissions equipment too like there okay the DF finally like I I refilled my DF tank yesterday I drove down about almost 40 Mi and it was still showing like half full but it just reset but yeah that’s

03:22 been an issue with some of the GM trucks I’ve owned too is it’s like the tank never shows full on my Ram it just as soon as you fill it up it’s instantly filled but not a big deal I’m just saying it’s just something that I’ve noticed like there’s just more issues with these trucks with the def tankes

03:38 for sure well they they do have a high flow which is nice but anyways let’s talk about the banks power so as you guys know GM did upgrade this engine for 2024 so different combustion different turbo few other things are different as well more power more torque and one

03:58 thing I will say is I did a video with a 2021 I believe which is the Gen 1 l5p so that had 445 horsepower and 910 lbet of torque compared to 470 and 975 lbet of torque so yeah there is a big jump for the horsepower well not a big jump but it’s it’s a jump for sure and there definitely is an increase

04:22 of speed going up this great in comparison especially when you have and consider 35 in tires now this truck has a 342 rear end and I would say with the banks power upgrades as I’ve said the power gets built a lot quicker the Boost gets built a lot quicker therefore I feel as though

04:41 you’re going to have more like performance getting up that grade Like There’s No Lack of power you don’t have to worry about if it’s 115° outside those rubber hoses that the manufacturer uses there’s not going to be a performance loss because you have solid pipe Now versus just more things that have

05:01 you know effects with the temperatures basically so I’m excited about that so I think reliability is better you have more air going into the turbo the turbo does spool up a lot quicker as I said in the last video too you don’t have like a lot of a noise difference but for sure

05:14 there is a boost difference I even have in a lot of cases I’ve noticed where my tires are spinning more off the line because that boost comes on a lot quicker so anyone saying that these parts are not going to do anything for your truck they’re obviously either a comp

05:30 competitor or they’re just haters of banks that’s the only way you can put it I know what I feel and I don’t get paid from Banks to say anything if I say something negative you know hey it is what it is but like my point is so far these parts have actually made a difference in how the Boost comes on

05:47 it’s night and day different so we should be to the grade probably about 15 minutes um let me show you guys some of the RPMs here with my truck my truck does have 35 in tires rounded off off let’s see how it does with some of the shifts we’re more likely in either

06:06 seventh or eighth gear I’m going to give it wide open throttle right now but yeah we’re going up a slight incline here and as I said every time you hit it I do notice that there’s more confidence in how that power gets delivered and it’s because you have more air coming into the engine and something

06:33 that um Banks has talked about too is Turbo surge so they do think about some of the negative effects of upgrades typically when you do upgrades to your car truck whatever you’re doing you got to pay to play I’ve modified a lot of cars in the past I have had Subarus that

06:51 I’ve done a ton of work to and when you do upgrades sometimes there’s negative effects to those upgrades one thing I saw and this is something that Banks talks about is Turbo surge they pretty much mirrored the manufacturer’s design for the turbo inlet so you don’t have to

07:09 worry about having an adverse effect with the way the Boost is coming on and turbo surge is something that you know you could feel it sometimes depending on you know what kind of Parts you buy I mean there are some lower grade Parts out there that are cheaper they will

07:25 give you some performance gains but they could have some negative effects as well so you have to keep that that in mind I have not noticed any difference in drivability with this truck and that is 100% what I go for I will buy the more expensive parts for upgrades if I notice

07:42 that they actually do take the time to test them and make sure that they’re not going so far away from the manufacturer that it it affects drivability and that’s something that is very important for some people and I do not notice any drivability differences between this

07:56 truck having these parts then without it so you guys can see the F comy right there we’re at 6.4 MPG all right so let me just drop down to about I got to drop down to 50 actually sorry all right here we go ready 3 two one go oh come on sorry guys we’re already at 75 miles hour

09:00

we got there really fast we still got some ways to go if we bring oh wow there it is told you guys I told you it makes a difference if it did one mile per gallon better I’d have been happy and it’s going 78 if we hit 80 get the bank stuff this stuff works it 100% works

09:33 79 80 it like I said for the people who were talking trash in the comment section in your face in your freaking face 81 keep going we’re going up a steeper part of the grade right now you talk trash and I got the receipts right here for you 82 I think it beat the Ford with the 1,50 conf to

10:01 torque in your freaking face I told you this stuff works 100% it got up I didn’t expect it to do this good I did not expect it to do this good I did not expect it to get to 82 mil hour I said if it gets to 76 it will pass in my book that it actually makes a difference we got up 7 mph quicker in

10:28

your freaking face for all the people talking trash I got the receipts right there and you know what I will admit to you guys it is 61° outside I’ll give that to you but I’ll redo this test in the summertime I will redo this test in the summertime and here’s what I’ll tell you it will go 78

10:46 79 mph it may not go 82 but it will it will beat with this truck did stock 100% so here is the axle out back let’s try to get a temperature read on this so we’re at 180 182 on that rear axle still got pretty hot on that turbo 331 here’s your EGR and the Boost tube on this this side about 158

11:34 160 and then that’s the hot side I don’t normally act like that too and I apologize if I offended some of you guys you know I try not to act like that but you know I get sick and tired of people saying that what I’m saying is not accurate because if I’m out here

11:51 testing stuff then at the very least I’m putting it on camera if you don’t like Banks or whatever that’s your own prerogative but but what I can tell you is these parts make a difference in the performance Department we went from 75 mph to 82 now I know that the

12:09 temperatures are a little bit lower than today but even when I did this testing back then when I did it I want to say it was probably in the 80° range it was not that you know hot outside and you guys can see right there I just ta the brakes and we’re maintaining 70 M hour let’s

12:27 see if I can get it to drop down some more come on the engine brake is on oh it’s not on there it is okay so here hold on let me let me get up the speed again okay it just it just went up a gear another gear it went up two gears so we’re restarting it a little bit now okay I’m going to tap the brakes

13:01 there it is I tapped it again look at that now I’m not going to say that these upgrades made the engine braking stronger my friend Ben barley he feels like it didn’t make a difference on the exhaust brake that is pretty dang good though that okay maybe it did make a

13:30 difference I you know honestly like I’m my foot is not on anything now that is pretty dang good actually maybe there is a difference with it a little bit cuz I don’t recall it being this good I just tapped the brakes two times and we got down to 50 m hour which is probably one

13:47 of the best ones I’ve done I haven’t done a ram yet so there’s that as well but with that maybe just maybe there is a slight difference on the exhaust brake performance because you I don’t know how it could make any difference but there’s very much a possibility that it

14:03 does I just can’t explain to you how my truck did that much better than the last time I did this test with a Gen 2 l5p durmax but yes this truck did extremely well but I’m serious tring to say this guys if you are going to put down a product then turn a camera on and prove

14:21 that it’s not doing anything for your truck do before and after I just showed you guys just now literally how well this truck did going up that grade we got to 82 mph I have not been able to get there ever with any durmax ever and you know what if I have a chance maybe

14:41 if I find a Gen 2 again maybe in the winter time I’ll retest it to see if it can get to 80 mph I’m willing to bet you it won’t get there I’m willing to bet you it won’t because that extra power is because of the extra air going into the engine you’re going to get an increase

14:58 that turbo spooling up fast F we got to 75 mph a heck of a lot quicker too and I dropped down to like 48 M hour so again you can say what you want but these parts are worth the coin whatever it costs I would do it I would do it again 100% if I traded the truck in next year

15:17 and did not get this stuff off of it I will buy it again I want to show you guys the time really quickly because we should be back in about maybe 15 minutes or so I got to do the 0 to 60 in a second but someone accused me on the Hemi test that I did that I took the car out that’s why the

15:37 Hemi went a lot faster so you know moving forward when I do my Towing test I’m going to just start showing you guys inside of the trailer that way we know that we’re not playing a game here the reason why I always show you guys like the mileage things like that is because

15:53 I want you guys know that it’s Apples to Apples it’s the same test it’s the same drive and it’s always within the same time frame I don’t try to you know make a truck look better than another one no one’s paying me to do this so I don’t care which one wins and I want you guys

16:07 to know if something doesn’t do well I will I’ll be honest with you guys you know so again I don’t know why I have to do this but I’m going to do it because I don’t want to give anyone an excuse to say well the reason why I went fast cuz he didn’t have a car in there that’s why

16:19 nope you’re going to see here in a second there’s a car in that trailer and you see what time it is it’s 10:42 I should be back in about 15 minutes I got to do the 0 to 60 test and then we’ll be heading back to the end point so I just want to make that clear and I will show you guys inside the

16:34 trailer here we go 30 60 qu mile we just got back back is 1054 now remember the miles from earlier on the test we went 36 and a half if you remember where we started off at you can go off of that Miles again I don’t have to do this because I don’t need to lie about stuff but I’m going to start

17:15 showing you guys because I don’t have anything to hide here and here is the inside of the trailer just so you know so got my wheels and tires inside of here I mean this stuff’s not heavy at all this is just yeah generator’s right there and there’s a car so you guys can see nobody’s lying

17:40 no one’s hiding I don’t care which truck wins or lose any test I could care less all I do is show you the facts that way you can make a more well-informed decision if you want to get a Toyota for I don’t care no one’s paying me to do this I do this on my own accord I spend

17:57 my own money I bought the parts that are on my truck right now and if I don’t buy something I will let you know but like I said I got the receipts here I got the receipts so if you’re going to talk trash about any company when I say when I talk trash I always give you the

18:15 backup I always go and test it you know and that’s what I did but I hope you guys liked the video this is one of my favorite trucks guys it really is and now that I have these Banks upgrades it’s it’s like a little bit better I just need to get some more information

18:33 and I’m actually talking with banks right now to get some more parts from them so yeah be sure to stay tuned for the yeah unveil the other things I’m going to be getting I’m super excited about it and yeah I I’m just I I’m sorry guys I I I get really frustrated when people call

18:49 me out without facts like you you call you’re basically calling me a liar and you’re not saying what I’m lying about so yeah I just and I apolog oliz to anyone that might have you know if you had kids around when I was say in your face I don’t talk like that around my

19:04 kids so yeah maybe I’ll put a disclaimer in this video when I say that but at the end of the day remember this you can do whatever the heck you want to do if you don’t see the value in adding upgrades to your truck cuz I don’t normally do stuff like this Ben and I were talking

19:19 about it and he was going to do it and then he kind of got me excited about it so I decided to test it out and I figured if I didn’t like it I could just take it off and sell the parts but I really like like these upgrades and I think that they’re worth the extra cost that Banks charges they are more

19:35 expensive than the other ones but I think that they’ve proven that they do a little bit more R&D and that’s what you’re really paying for you’re paying for the name that these people actually do take time to test their stuff their products are typically a little bit

19:51 better than what I’ve seen from others like I’ve seen a lot of people say they’ve had issues with check Eng lights on the codair intakes well they haven’t even released the codair intake for this truck it because they’re trying to develop it to where it doesn’t throw a

20:02 check engine light with the extra a that comes through that obviously that new intake system so hopefully in time maybe I will get that I’m not a huge fan of those things because I’ve seen where they could actually hurt your performance but yes like I said Banks doesn’t pay me and the parts that I do

20:20 sell from them like if you use my discount code in description below I do get a commission from that but I have to get people to buy that stuff so yeah me doing my videos Banks is not pay me to say what I say and do what I do if I say something negative it is what it is

20:35 they just have to deal with that so I’m done rambling I’m done talking let me know you guys’ thoughts in the comment section later
