Reading the web site, it does not say anything about improved performance, just about changing some settings if you change gears or go to larger tires, etc...very similar to the AEV ProCal. If you want to try different performance settings check into something similar to the Diablo programmer or such. Some report minor performance increases, but most are just seat of the pants butt dyno stories...

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
