Jeep Grand Wagoneer Throttle Control Module - aFe - Sprint Booster - `19-`25 is a dedicated throttle response controller for 2019–2025 Grand Wagoneer models. This plug-and-play module sharpens drive-by-wire throttle input to deliver crisper, more immediate acceleration without altering engine management.

The Sprint Booster works with the vehicle’s electronic throttle control (ETC) to reduce the lag between pedal travel and throttle response. Drivers will notice improved off-the-line response, more confident passing maneuvers and smoother downshifts on automatic transmissions. Installation requires no cutting or splicing; the module connects to the OEM plug located behind the accelerator pedal and does not interfere with injection, ABS or other systems. Tunable modes and safety features let you adapt the behavior to street, spirited or restricted driving.

Features

• Three operating states: Off (factory), Sport (improved response), Race (stronger response)
• 18 acceleration programs — nine settings per Sport and Race modes for fine tuning
• Valet mode with three selectable limits and Pedal Lock for anti‑unauthorized use (PIN protected)
• Simple plug-and-play installation to the OE connector; no wire cutting
• Compatible with 2019–2025 Grand Wagoneer L6/V6/V8 applications and does not alter ECU functions
