Well if you want to do the tune yourself and play around with it you can go with HPTunners. If you want something reliable that offers lots of different options you can go with a vectors tune. There is also the option of going with a westers tune.

Vectors is the tune that most people get. It offers about 8+hp and 10+tq and is what I have in my car.

Thats some information on the Vector Tune.

My knowledge on the Westers Tune is very limited since I never looked at them much.

I just went out of warranty but I have never heard of anyone on the forums getting rejected for warranty work because of a tune yet. Intake and exhaust I have heard of before but not a tune.
