Vauxhall Astra VXR tuned in Thetford, Norfolk.

Before tuning we checked this vehicle over as we always do. The one way valve had failed on this, which was causing the rocker cover to leak constantly in places. The vehicle also had a misfire. This was down to the completely wrong plugs fitted, so we swapped these out with the stock GM plugs. After this the vehicle ran much better and we tuned it.

Now running 290BHP.
