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.

so far I have tried it only on the performance mode and have not taken it to a track to see actual #'s ,however i have taken a short run inroads I normally travel abiding the speed limits and trying to get mileage and have exceeded normal mpg.up and down hills garage to garage and over 35 miles 31.7mpg.I'll try it on a road trip and reset it to best mileage program. 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.
