What is good compression at 1 mile above sea level? Mine reads about 85 on all rotor faces. In the factory manual it says the minimum at my altitude is about 65, so is my compression good then? My car is pretty slow right now, and I'm trying to figure out why.

well if the book says its ok then keep looking, at least your motor is good https://www.nopistons.com/forums/pub...#>/biggrin.png
