i recently bought an 03 cobra and love the car, but i want to tune it and put it on a chassis dyno. Already has some mods, intake throttle body, exhaust, and 2.7 pulley. Whats a good tuner, diablo? sct? do they write a tune? does the dyno shop tune it according to the dyno numbers? I really dont have a clue bout that, but i jus want to make sure its done right? I'd really appreciate some input and advise. Also bout what kinda rwhp could i expect to see? Thanks.
