Thanks MPGeo, no problem, I got the numbers in this weekend. Cylinder 1 - 4, 135, 125, 125, 115 psi respectively. Factory is 128. I'm good with that, so no restore additive. I'll be getting gas tonight, so it will be my first tank of gas check. I also received the ultra gauge last week, and I'll be starting to do A-B-A testing with it.

Next experiments will be fuel system cleaner (obviously cannot do A-B-A testing), and weight reduction (I will do A-B-A testing) just obvious items that I don't need.

I'll check back in a week or so.

Cheers to all the responders
