the "*" is to let you know that the parameter has been modified. Once you install the tune. It's done

truth couldnt be spoken any better

List your modifications and what tune you have and what parameters.

whats your global spark advance at?

I take that back. I got mixxed up with something else.

And about how much timing does 1% increase/decrease?

How much timing difference is there between the 87 & 93 octane tune?




2007 - Ford - Mustang - 4.0 - AUTOMATIC - V6 - U7145 (NO COMPLAINTS!)

I'd mod the car a little more before I changed anything else. I own a well modified 07 4.0L V6. I do understand that the guys at Diablo did leave some power left behind in the tuner but that's because they are putting it into production and people DO&WILL play with it and need a little more cushion ...
