I was running 93 Octane correct.
The tune took a long time to get done right, But originally i was going to run more boost, and wanted too. But my headgasket/headstuds were holding me back. I wanted the car to be relaible, I didnt want a RACE tune and a STREET tune, what i Ran on the Track i Ran on the street.
the sweet spot for my car was 19 PSI and 20 Degrees of timing.
I had help from other DSMers, a Pro Shop, and Lots of hours of tuning...
If I had a better tuning program such as DSM link and a Headgasket head studs. I could have run closer to 22-24 PSI. which would have probally got me to the low 12s.
Race Gas, Cams, and 25 PSI would get me in the high 11s.
