I am a huge fan of the Bama X4/SF4 Power Flash Tuner and would highly recommend it. The tuner will really wake the car up (as you can see) and it also comes with free tunes for life! As you mod the car in the future, the Bama team will write you new tunes at no cost!
Hope this helps and let me know if you have any questions!
So far guys have been very happy with their Unleashed tunes and MAP and FFtec have been making good numbers with their COBB Protunes. I've only heard 1 customer review on Livernois and they really liked it as well. A few of these have been autos, including the Unleashed tunes I've heard about.
