• De-install the Brainbox of RaceChip XLR.
• Return your car to stock tuning by reconnecting the stock
pedal sensor directly with the throttle pedal.
• Check the throttle response, with the car stationary at first
and then on an empty road. If the throttle response is still
bad or patchy, we recommend not driving the car. The
problem is probably not caused by RaceChip XLR but by a
malfunction in a component in the throttle pedal.
