Vauxhall Astra VXR - CustomPro remap

Vauxhall Astra VXR - CustomPro remap

Recently we had this Vauxhall Astra VXR in for our CustomPro remap and an intake kit which we supplied and installed. Initially the owner wanted to install a dump valve, but once we explained the negative effects a dump valve can have on this engine, he still wanted the noise produced, so opted for the Ramair intake kit.

Once we installed the intake the car was strapped to our rolling road where we began tuning. With this particular car we also raised the rev limit to 7,000 rpm from 6,500 rpm which helped us gain 45 bhp at 6,500 rpm!

Power gained: 30 bhp

Torque gained: 64 nm
