Compression check been done? Is it breaking up on the top end? Post the dyno sheet that will help a lot, make sure it has the torque curve also. Rpms would be nice instead of wheel speed.. The numbers are extremely low for any dyno. Should be at least 450rwhp @ 20psi.

I had the shop do compression test back while I was deployed and I asked them about it and I was told "the engine popped up right where it should be for one of these engines. All 6 rotor sides were within 1 psi of each other around 77 on the gauge"

Hopefully they did it wrong or didnt hold the throttle open, cause 77psi all around is pretty worn out, recent rebuilds are around 110psi and anything under 90psi is probably starting to show signs of age.

Had another shop use a normal compression tester and it showed right around 110 psi across the board so ruled that out. Found some boost leaks and other things and cars running strong now but another run on the dyno now shows the clutch not holding up to the power so I've got an ACT 6 puck extreme clutch on the way. Funny thing is the shop that did the compression tests that showed 77psi uses a fancy computerized rotary compression tester and even thought those numbers to be good and said he hardly ever sees 100psi or more.

Most likely between 450-500 depending on the tuner
