Manual turbo control, max 12-13 PSI
Compression last tested at 170-175# on all cylinders
20lbs vacuum at idle
12 deg. advance timing
I think that's all the relevant info, let me know if I'm missing anything.
Anyways, this thing runs solid- pulls well in almost all situations. The issue I'm running into is during >75% throttle sustained pulls it will always stumble after a few seconds of holding 10-12 lbs boost. Typically this is during a pull from 70 - 100, I'll be cruising at 3k, and as I near 4k and I'm holding boost above 10lbs it will break up and I have to quick get out of the throttle and it's fine.
I'm thinking likely a fuel issue? I don't have any issue running through the RPM range when I'm banging gears but those long sustained pulls in boost don't ever hold on.
