Vauxhall Astra J VXR tuned on the rolling road.

This Astra J VXR had all the hardware for stage 3 however the intercooler wasn’t up to the job. Intake temps shot up as soon as the car was loaded on boost. This killed the BHP at the top end of the run. Still gained a lot of midrange torque though and transformed this car!

Figures: 311BHP / 380LBFT.
