I used on a 2021 GMC Sierra 1500 5.3 for a couple months before trading the pickup.
Standalone Throttle Sensitivity Booster
PedalMonster is the first OBD-II connected throttle sensitivity controller for gas and diesel vehicles and is tuned to eliminate your factory dead pedal feel and throttle delay. This kit is controlled via the Banks mobile app on your phone or other mobile device (iOS and Android) PedalMonster is the only module of its kind to offer safety features like ActiveSafety®, Reverse Safety, and Adjustable Low-Speed Trim. No other throttle booster has the same level of safety, ease of install, and additional features.
