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 is tuned for street and daily driving. PedalMAX Terrain is optimized for 4WD mode, crawl control, and off-road throttle response on trail and dirt.
