A friend of mine is running pre turbo Meth injection. He was told time and time again that the high comp engine would only take a max of 10 psi. he has his up to 16 psi. He has a msd knock sensor and it still has very low knock. I have driven the car my self and i would not argue with its performance. I await the day he fits a egt to it but my gut fealing after seeing the plugs is all good my friend.
