If you get a Diablosport tuner, make sure it is model U7145. The was 2 different versions, one for 05-06, and one for 07's.

As stated above the diablo sport or the sct xcal2 either one will work well for you I prefer the sct because I have one. My tunes are from brenspeed and they are kicka**. B amachips and VMP are good as well. Dont buy the tuner with canned tunes and then get a custom tune just buy it from one of the custom tuners mentioned it will cost the same and then you'll kick yourself when you spend an extra 75 bucks getting a better tune.

I have the Brenspeed tune and Steeda UPD's. I think they both madeequal improvements. The UPD's are a snap...(well literally for some people bolt wise).
