Well, one of my customers was getting his 05 tuned (after cam install) and he was very excited to make 430rwhp and 390rwtq, and then they pulled a new Z06 onto the rollers. He asked if it was stock and they said, no, we just put a mild cam and 1 7/8 long tubes on it, we are going to tune it and get all of the details worked out. Well, an hour and a half later the thing was spinning the rollers to a tune of 708 rwhp and 695 rwtq!!!!!!!!!!!!!!! My customer said the car sound relatively stock (cam wise) and the headers really gave the car a unique sound! Holy sh*t, a small cam and headers to get over 700 rwhp! That is truly amazing! :cool
