  1. Astra G
    Hi, Recently I bought a boost gauge into my Vauxhall Astra g. Now I am seeing that the max PSI that I can reach is 0.8 PSI. Is this normal for a 1.7dti Isuzu Engine. I bought this car second hand so I don't know if it is remapped or stock. Thanks

    I've had an idea for raising boost on a cdti engine, may be silly or may have been done before. Basically, your maximum boost i believe is limited by the ecu when the map sensor reads a certain pressure. So in theory putting a resistor in series with the signal wire from the map sensor woul give...
