Rather than risking the motor Im thinking about getting it tuned to be on the safe side until I get mod crazy. Found an XCal 2 but not sure if it will work for me.

These are the pics:





It says stock so im assuming its not married? What does 5 changes left mean?

Heres my dyno(notice exhaust at the end) and heres my sheet. A/F hit 12.0 near the end.

I only have intake/exhaust with a catted mid pipe. No major mods planned but I dont want to risk anything in the meantime.

Do I need a tune or should I just run 93 octane or octane booster?
