Test with all plugs out and at wot

I'm gonna say look for 120 psi or more +/- 10%

what he said, probably more like 115. Don't get bent out of shape if its lower or higher than that. Most compression gauges aren't calibrated,I tell people, I've got a buying(reads low) and selling(reads high) gauge, which one do you want me to use. Look for them to be close to the same number, rather than worrying about the number itself
