the main thing you are looking for is variation between cylinders. of course overall low numbers are not good but you will most likely see a very low number in a bad cylinder.

I have CP 8.5:1 pistons and a compression test will yield 150-155psi per cylinder

on my 9.0:1 cp i get 170psi. it also will depend on ring gaps.

all my cylinders were at 140psi.. i gap them for fi/turbo set up i guess 140psi is good.. thanks
