Now that all the codes are gone I would like to know what company's people on here are using for tuning/chipping? I saw that APR and ECS sells tunes for our cars,anyone else? Seems like they both sell the same exact thing. Also who sells a good sounding exhaust for our cars? Any youtube videos I can watch to get a idea of the sound? Or if someone on here has a exhaust on their car do you have a video of your car? Im looking to do some upgrading to the car and would like more power. Seems like a tune/chip and exhaust would be the right start. Anything else I could do? I really want this done before waterfest because I would like to race when I go there.
