when the car was running the 2 bar it was apparently ok at first but then it started "overboosting" (stalling)... but now that u mentchen it I dont remember it behaving like this before i replaced the spark plugs

I just lengthenned the pin to the wastegate as I was told to do.... Is there something more to it? If so, please tell me

The gap on the plugs... how do I know what is right??

Olaf
