its tunned for 15psi right now it safe to run up to 22psi if tunned for it.
It was dyno tunned last summer and made 409hp@8200rpms it redlines @9200, I only drove the car one season and that was last year and I never put it on the road this year because I have been to busy getting ready to move. I have not done a leak down test lately but I assure you that the car runs 100%! If you were or anybody were interested I would have no problem checking the compression, if it makes you feel better!
