Who said i/he was entirely blaming the dump pipe ? I just said it played a part in stuffing up boost levels and as well as his injectors weren't too good causing, like you said, the motor to lean out and go bang.
And no he wasnt giving it too much, it was still in the run in period (obviously gave it a bit sometimes, but not constantly).
So its pretty much what you said, too much boost, shit injectors....How is that the most stupid comment ever made on SAU ?
