2021 Chevy Silverado owner reacts after tuning his truck

Steven uses his 2021 Chevy Silverado 3500 HD Duramax to tow a car trailer all over the Southwest. He called Banks to add more power and kill the throttle lag. He installed a Derringer tuner, PedalMonster throttle booster, and iDash DataMonster and gained 81 hp / 144 lb-ft, which improved his passing ability, hill climb speed, and completely eliminated the dreaded throttle lag.

No other performance parts manufacturer knows more about the Duramax engine than Banks Power. Don't believe us? Google it.
