Good Results

Reviewed By Thomas D (MANNFORD, OK) Reviewed for a 2004 Chevy Corvette —4/7/2013 7:29 PM

Was a little disappointed that I had to update the program straight out of the box, but the link and download worked easily and quickly. Has lots of set points, which is fun to tinker with. Since we only have 91 octane readily available in our area, I had to add octane booster to eliminate the pinging. Bottom end response is noticeably stronger, and the firmer shifting is just what I wanted. Mpg seemed to pickup a bit too, but that is offset by the needed octane booster.

Easy installation and performance difference

Reviewed By Scott S (Williamsville, IL) Reviewed for a 2006 Chevy Corvette —10/29/2013 6:09 AM

The installation was straight forward with easy to follow directions. I'm not seeing any difference in mileage, but I can tell, by the seat of my pants, that there is improved acceleration and firmer shift points. I've calibrated with the 87 octane parameters. I may try the 89 octane calibration as I can get that fuel for the same price as the 87.
