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.

I'll let you know what happens. I do hypermile when safe. It is great to have all the power and still be able to economies.
