I decided to remove my Demolet Intake and Bama Tune since it was giving me constant problems. Car is back to stock and runs perfect. However, I do miss the fun factor of the intake tune/combo. I still have the XCal II tuner. I know I can go and adjust some things on the stock tune with the tuner such as firmer shifts. Does anyone with expirance on this tool and a stock auto know whats a good starting point to firm up the shifts, advance timing, etc. I'm currently using 89 octane. Any input is greatly appreciated!!!
