Throttle response when YOU need it.
Bottom Line
No. PedalMAX only modifies the electronic signal between your accelerator pedal and the throttle body. It does not alter your ECU, engine calibration, or any factory hardware. It’s fully reversible — unplug it and your vehicle returns to 100% stock.
Yes. PedalMAX works alongside any aftermarket tune or programmer. It operates independently of the ECU calibration, so there are no conflicts regardless of what tune you’re running.
Completely. PedalMAX plugs in between the factory connectors. Unplug it and reconnect the stock harness — takes about 2 minutes. No trace left behind.
PedalMAX controller unit, vehicle-specific wiring harness (pre-terminated — no cutting or splicing), adjustment dial, mounting hardware, and quick-start installation guide.
PedalMAX – built to increase throttle response and deliver sharper pedal performance. Adjust from stock feel to maximum pedal response on the fly.
PedalMAX Terrain – takes control a step further by allowing you to both increase and decrease throttle response. Dial it up for quicker acceleration, or dial it back for inexperienced drivers and improved control in sand, rocks, mud, and other off-road conditions.
TractionMAX – engineered for super high-horsepower vehicles where traction and throttle control are critical. It includes all the features of PedalMAX Terrain, plus user-adjustable throttle control to help eliminate tire spin, manage power delivery, and give you the advantage over the competition.
