Well still no joy! Tested my actuator and that was ok. Took the vac hose off with the brass restrictor and put a straight bit of hose on and reset the ecu, I was only getting 8 spi of boost but the check engine light came back on which proves that what ever is bringing the light on is also causing the highboost pressure, could it be sensor related? I am still getting the same fault codes, could the speed sensor do this?
