Yup 80-120psi is what you should get.That takes the decomp into the result.Without decomp it would be well over 200psi.
ya, I thought the decomp could have an effect on the reading.
in a perfect world if I have 12.5:1 then I should see about 183psi, is there a correction factor that can be applied taking the decomp into consideration?

Would depend on you valveclearance,Timing and probably other factors.80-120psi is accurate enough to tell if everything is right.
Thanks Steve
