I had a 6765... put it on and with the wastegate set at what should have been 18-19 psi the car was going to 30psi+ and quickly too. I had to crack the gas to avoid more. The minor porting I did got the spike down to 3psi and 2psi of creep down the track. I was using 110 and meth so the inital testing had some cushion. Its not a huge amount of work to take it back off, but you may want to reconsider. Just want to let you know what could happen.
