JMS PedalMAX eliminates throttle lag in Ford F-150 trucks, delivering faster throttle response for towing, hauling, daily driving, and weekend adventures.

PEDALMAX THROTTLE RESPONSE CONTROLLER
The original throttle response controller. JMS introduced this product category, setting the standard for pedal signal optimization without ECU modification.
Fix factory throttle lag in your Ford F-150 in minutes.
Modern Ford F-150 trucks use drive-by-wire throttle mapping that softens or delays pedal response. PedalMAX recalibrates the pedal signal to deliver a direct, immediate throttle feel.
PedalMAX installs inline with the Ford F-150 accelerator pedal sensor and modifies the output signal in real time.
No apps. No Bluetooth. No external devices. All adjustments are made directly on the unit.

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.
