how many miles do you have? are you stock? i have about 1600 miles and just have a k&n filter. i did notice a nice diff w/ the k&n - car is much smoother now and sounds a lot better - do you post on evolutionm.net?
im definately interested in heading down in the spring - i thinks he likes ecutek but i’d like to use the cobb protuner since you can flash back to stock when you have to bring it into the dealer
