The Edge Products 28862-D2 Amp'D 2.0 throttle booster fits 2020-2026 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax, plus 2020-2026 Silverado/Sierra 1500 and 2021-2026 Tahoe and Suburban with the 3.0L LM2/LZ0 Duramax. It targets the soft initial pedal travel built into the factory drive-by-wire calibration. That delay shows up as dead pedal off the line, when merging, and when pulling a trailer from a stop.

The module plugs in between the accelerator pedal and its harness and reshapes the pedal signal before it reaches the ECM. It does not change engine tuning or add horsepower; it changes how fast throttle demand ramps with pedal position, which also gets the turbo spooling sooner. Control is through a wireless Bluetooth switch and a phone app, so nothing has to be mounted or wired in the dash. No core required.

• 5 Preset Throttle Curves: step from mild to aggressive pedal response to suit towing, daily driving or empty-bed acceleration.

• Wireless Bluetooth Switch: change settings or return to stock without a wired controller in the cab.
• Plug-and-Play Harness: connects at the accelerator pedal with no cutting or splicing.
• Works Stock or Modified: runs alongside stock or modified powertrains.

Vehicle Fitment & Technical Installation Notes

Fits 2020-2026 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax, 2020-2026 Silverado/Sierra 1500 with the 3.0L Duramax, and 2021-2026 Tahoe and Suburban with the 3.0L Duramax.

Installation Tip: Do the install with the key off, unplug the pedal connector, and seat both harness connectors until they click. Route the module and harness away from the pedal arm and floor mat so nothing binds the pedal at full travel, then pair the switch and confirm stock mode before trying a preset.
