Sharper throttle response, professionally calibrated to your car — not a generic plug-in guess.
Acceleration that jumps instead of sharpens. A device zip-tied behind the pedal, ready to rattle loose. A "universal" setting that was never actually matched to your car's throttle map. Plug-in throttle controllers are simple hardware, but the difference between a good and bad install is calibration — not just plugging it in. Pro Car mounts the controller properly, walks you through the sport/eco/standard modes, and test-drives before handoff.


We plug the controller into the accelerator pedal harness, mount the control unit securely and accessibly, calibrate and demonstrate the driving modes, and test-drive to verify response.

Secured so it won't rattle or come loose.
Not a generic universal setting.
We confirm the feel before you do.
Removing it restores your car exactly.
