if i had to spend 5-6 thousand that would be fine. I think my 03 has around 280hp, i would like around 330ish, but no spray(nos) bin there done that with my 1/4 mile car
You don't need $5-6000, a K&N with a tune should have you in the ball park of 315-320 I think.
I may be wrong, but I have a hard time believing that a K&N filter and tune would give one 35 HP. Please define tune? I'd love to add a good 40 HP to my 06.
