I had a dyno run recently and only got 157.8 rwkw. Car has twin dumps, 3inch exhaust. I had a compression test done and got:
1: 130psi
2: 130psi
3: 140psi
4: 135psi
5: 125psi
6: 130psi

Obviously this is low. The car also blows a little smoke on deceleration and idle.
Does this sound like rings, or valve stem seals. Car has no problem boosting, got up to 11psi on dyno, but now gets 14psi since i fitted ebc.

Did you try a Wet comp test too? By putting a small amount of oil down each cylinder and then checking compression? This will help let you know if its rings or not.

There is not much variation in compression test and that power figure is about right. i would not be concerned. even if you think numbers are low, i would say it was the way it was done.
