it limits just after it peaks, if that makes sence, if i watch the gauge, when i floor it , it will go round to 20psi, and then just as it starts to drop from the 20 psi, it cuts, rev counter bounces and then hell of a bang, or some times a flame out the exhaust,
i do have a turbosystems chipped ecu to try on it, do you think this will help, thanks for your help to...
