I have a DiabloSport i3 that I got a few years ago to use on my 2011 to disable the AFM/DOD. It came with a couple tunes installed, like a 87 octane mileage tune, a 93 octane performance tune, and the ability to modify parameters. It can also data log and you can get customized tunes made and upload to it via a pc usb cable and install. I use it on my 2012 now.

I really don't know. I only had my 2011 for a couple weeks before I got it, and mainly did it to turn off AFM/DOD. Then a month later the 2011 was totalled by a drunk driver.Gooffeyguy- Do you feel the tune helps your performance?
