Frankly I am a bit disappointed with the overall performance of the engine. It runs good but doesnt shine anywhere. Its pretty torquey but doesnt boil the skins off yet it lacks a high end. I am assuming I can tune it into better shape but not to the level of what I expected.
This with the other data you supplied, speaks directly to the 168 to 175 pressure reading you obtained.I'm kinda thinking the gauge you were using is extremely optimistic.
If the Scr truly is 9.7,
and your elevation truly is ~2500feet, then
then the pressure would be waaay down from those numbers.
