Product Details

The BFI OBD-II VR6 Performance Enhancement Moduleis is designed to not only increase power and throttle response, but to also smooth out the power as it is delivered throughout the RPM range. The Stage 1 VR6 PEM offers noticeable performance gains over stock on the torquey VR6 engine. Carefully mapped adjustments to the fueling and timing allow the most to be extracted from VW's VR6 powerplant. The PEM also increases the rev limiter to 7,000 RPM and deletes the top speed governor for those taking it to the track. This file is tuned on 93 octane, however the ECU will pull enough timing if you had to run 91 octane.
