2005 GTX Compression Readings
On my 2005 GTX, I read 175 psi in each cylinder. On my 2005 GTX Limited that has the supercharger, I read 150 psi in each cylinder.
The standard GTX has a compression ratio of 10.6:1 and the supercharged GTX has a compression ratio of 8.4:1. That being said, each ski will have a different normal PSI. I have looked in the service manual but was unable to find it. Are those the correct values?

Sounds right but to check real cylinder leakage do a leakdown test
