Step-By-Step Performance

Eric Ware has a lot of good things to say about the Banks products even though he hadn’t planned on buying any for his Duramax-powered 2020 GMC Sierra. “I told myself when I purchased this truck that I was going to keep it stock,” Eric recalls. “But then I started doing research and Gale Banks seemed to be the only one out there that fully understands what a diesel needs in order to function optimally.

“I purchased the Derringer Tuner with iDash SuperGauge, PedalMonster, Intake Resonator Delete, Boost Tube Upgrade Kit, iDash Stealth Pod Mount, and Monster Exhaust System. I already had an aftermarket stock oil air filter, so I went with the Intake Resonator Delete kit because the Banks red-coated pipe looks great. The iDash Stealth Pod Mount looks like the factory did it, and the Monster Exhaust System installation went together without a hitch.”

“I purposely did my installs in progression so I could measure the improvements after each install. I am very pleased with the horsepower and torque increases. The iDash functions far better than I thought it would. The PedalMonster performs better than advertised. The Derringer Tuner far exceeds any other turner on the market in both performance features, while safeguarding the engine and transmission at the same time. Gale Banks is one of the last of the real McCoys and continues to produce the best-designed products using quality materials. I have several customers that visit my shop that I will be recommending Banks part to. I used to be a big pro-delete advocate, but Gale has completely turned me around on that fallacy. So, thanks a lot Gale, you gave me the go-fast and taught me how to do it right.”
