A lot of diesel owners assume the only way to make a Duramax run hard is to delete it. That’s the problem we put on the table here. The combination is straightforward: a Banks Derringer Tuner for added power and a Banks Ram-Air Intake System to reduce intake restriction and improve air mass into the turbo. That gives the engine a cleaner, less restricted inlet path and tuning that adds performance without leaning on a chipped-and-deleted strategy. The takeaway is bigger than one run: emissions-compliant power still has to prove itself under load, and that’s exactly the standard we hold it to.
The video sets up a comparison between two Duramax approaches: a Banks EPA-compliant tuning package and the more common fully deleted, chipped configuration. Rather than framing the build around emissions removal, the focus is on how much performance can be extracted while remaining emissions compliant. The hosts position the project as a serious performance test, not just a cosmetic install, and immediately suggest that the finished truck should look and perform dramatically differently from stock.
The first major modification mentioned is the installation of the Banks Derringer. In the context of the build, the Derringer is presented as the opening step in the go-fast package and as part of the compliant tuning strategy. The discussion makes clear that the truck is being assembled around Banks hardware rather than around deleted tuning, establishing the engineering direction of the project from the start.
A notable moment in the video is the appearance of Gale Banks himself as a guest during the installation and discussion. His presence reinforces that the project is centered on Banks engineering and on emissions-compliant performance development. The hosts treat his involvement as significant, both because of his reputation and because the truck is being used to demonstrate what compliant tuning can achieve against the expectations set by deleted diesel builds.
The recap repeatedly returns to emissions compliance as a central theme. The implication is that many enthusiasts assume emissions equipment and compliant tuning inevitably cost substantial horsepower. That assumption is acknowledged directly, with emissions hardware described as something many people believe "kills horsepower." The build is intended to challenge that idea by showing that carefully engineered airflow and tuning improvements can still produce meaningful gains without deleting the truck.
Another key component installed on the Duramax is the Banks Ram-Air intake. The video attributes a gain of 20 horsepower to this intake system. In the sequence of the build, the Ram-Air intake is presented as a foundational airflow upgrade that complements the Derringer and supports the broader compliant-performance strategy. The emphasis is on measurable improvement through hardware changes rather than on bypassing factory systems.
The project is not left at the level of shop claims. The hosts explain that they are taking the truck to Mountain Mike's event, turning the build into a direct real-world challenge. This shifts the video from installation and discussion into competition intent. The truck is being prepared not just to feel stronger on the street, but to prove itself in an environment where performance can be compared against established diesel competitors.
The benchmark identified in the video is Scott Bergeson, described as the record holder with a Cummins. That reference gives the Banks-equipped Duramax a specific target and frames the outing as an attempt to pressure a known leader rather than simply make exhibition passes. The hosts state that they believe the Banks D-Max can give the record holder trouble, which is the strongest performance claim made in the clip. Even in this short segment, that claim is tied to the compliant Banks package rather than to a deleted setup.
Taken together, the segment presents a clear argument: a Duramax equipped with Banks EPA-compliant tuning and airflow upgrades can be built as a legitimate performance truck, not merely as a compromise for owners unwilling to delete emissions equipment. The Derringer and Ram-Air intake are the named components, with the intake specifically credited for a 20-horsepower increase. Gale Banks' appearance underscores the engineering credibility behind the package, and the planned run against a record-holding Cummins provides the practical test. The video's central point is that compliant diesel performance can still be aggressive enough to enter serious competition and challenge expectations shaped by chipped-and-deleted trucks.
