I went back and read the past few posts and just to clarify, did you pickup 2 PSI just adding the super tensioner? Did you change to a 3.4 at that time? I was thinking you were at 7.5 PSI on a 3.2. If you are in fact at 7.5 PSI on a 3.4 your car is exactly where mine was with the same setup. Are your RWHP numbers at 560 in your signature made at 7.5 PSI? If so you are right on what my car made factoring in the auto verses the manual. If that is the case from what my tuner says we have a setup that does not have as much restriction as some others, which is a good thing. He said for some reason some cars just do better with less boost than others. If that is the case then I think I can give you some good information on what will happen with the different pulleys front and back given our cars made almost exactly the same boost, crank HP on the same pulleys.
