As mentioned before, I'm going to get my car tuned for the new headers tomorrow. The shop I'm taking the car to is called Carolina Chassis Dyno, near Columbia SC. Anyone have any info on this shop and are they reputable. I'm not looking for a custum tune, I just want to get my Brenspeed canned tune adjusted for the headers. They are a listed SCT tuner and specialize in Ford vehicles. It just happens to be the closest place to where I live (Augusta GA).
