I wanted something that I could program myself instead of sending of my PMC to someone eles to program. I was able to change my tire size to compensate for the 33in tire I installed, also was able to change my shift point and shift firmness as well. It also came with two performance setting, an 87 and a 91 octane. I used the 87 octane in my 3.7 liter and I got a boost in performance and mileage as well. Which made me very happy.

Real easy to program and install. Took me about 30 minutes to hook up. I left the USB cable attached in velrco behind the access door for fuse box, in case I ever need to adjust in the future when I get gears. Only issue I had is the box attempted to some update with the firmware and would fail. I emailed there support and they said to ignore it. I was still able to calibrate with no problem. CD did not come with my product neither I had to email support to get the link to download the program.
