Yeah that would make sense, I am gonna get the custom tunes done over summer i hope... but for $60 each its kinda out of my budget for now, plus I havent done almost anything performance wise except the gryphon, a gott's mod, and just put on a cat back gibson exhaust. then I needed new tires so I got some 35's on there now. It looks great, but i gotta save some $$
I think I will change it over to the performance tune to see if that helps, but with the big tires the extra low end torque might come in handy
