Hey, I figured this out! My Compression tester pushes right into the port (no hose). I went to Silver86's the other day and we compression tested his engine, we got 45-50 psi bounces with his gauge (with a long hose). We tried it on my '91 and got 65 psi pulses.
I feel stupid, the difference is the amount of air to compress in the hose going up to the compression gauge. I should have thought of this before.
The '91 gets 110 psi on his gauge (so don't feel at all bad about 55 psi).
Just thought I would clear this up.
