my 08, but am completely clueless as to what this will get me. A member claimed in another thread that the 08's could be tuned to 300 hp with no additionally parts. If this is true I really want one. I have so many question about it though. Like will a Tune void my warranty? (I'm assuming yes) Is there a way to mask a Tune? I know I could go with a Cobb AP but is that the best way? Is a pro tune better? I know an AP will give me a variety of different maps and ECU set ups but if I just want a straight tune to give me a good hp gain what am I looking at?
