Derringer Tuner Adds Low‑End Torque to GMC Denali

Matt Rhoades, a member of the Banks Test Pilot program and owner of a private underground utility company, relies heavily on his 2024 GMC Denali for business. The Iowan drives between 250 and 500 miles daily for contracts with wind farms, gas companies, and US Cellular. For someone who tows a fully loaded 42’ toy hauler weighing around 17,500 lbs, performance matters. According to Matt, the new Derringer has been a game-changer. “I’m pretty ecstatic!,” he says. “The low-end torque on this thing is so powerful. 

“I used to take it easy on the road, but now, I don’t know how many people I’ve passed!” With the Derringer set to level 6 for towing and level 3 for city driving, Matt notes he has “plenty of power,” and when paired with the PedalMonster, the experience is nothing short of awesome. “Because I can set my throttle’s sensitivity, it feels like a rocket booster that mixes with the Derringer’s power.

Having the upgraded iDash Pro as the interface also earns high marks. “I love the integration with the phone. The ability to switch things around on your gauges using your phone makes set up so much easier. The screen is super crisp and easy to read. And, being able to do over the air updates is also a big plus for me.”

“Banks has exceeded all my expectations,” Matt concludes. “People keep asking when a delete is coming for the 2024s, but honestly, you don’t need one. The Derringer and PedalMonster combo keeps your emissions compliant and still delivers all the performance you’ll ever need.”
