PedalMAX Drive By Wire Throttle Device

The PedalMAX Drive By Wire Throttle Device from JMS is an electronic throttle response module engineered for General Motors full-size trucks from 2008 through 2016. This throttle booster modifies the signal between the accelerator pedal and the engine control unit, delivering a more responsive throttle curve without requiring any modifications to the vehicle's factory wiring or computer reflashing. The device provides measurable improvement in pedal-to-power response, a critical upgrade for drivers seeking sharper acceleration feel in stock or lightly modified trucks.

Installation on compatible GM full-size trucks is straightforward, integrating with the drive-by-wire throttle system standard on these model years. The module sits between the throttle pedal sensor and the ECU, intercepting and reshaping the voltage signal to eliminate inherent pedal lag built into many factory throttle maps. The compact design—measuring 6.25 x 2.8 x 8.7 inches and weighing just 0.75 lbs—mounts cleanly beneath the dash without occupying significant space. No vehicle disassembly beyond basic panel removal is required, and the device is fully reversible.

This throttle booster is ideal for truck owners running 2008–2016 GM full-size platforms who want improved throttle response without electronic tuning, warranty concerns, or complex installation. Off-road drivers, fleet operators, and enthusiasts upgrading trucks for towing or performance benefit most from the more immediate throttle engagement. The PedalMAX works with stock engines and pairs well with other bolt-on upgrades like intake systems or exhaust modifications, enhancing the feel of any performance package without computer intervention.
