I've got an 05 with 22k miles. It has a Paxton system that was installed by Woodhouse a long time ago by the original owner. The car runs great, but I'm considering having headers installed. Will the stock computer compensate for the headers, or will I need to have it re-tuned? I'm struggling to find a shop near me that will/can tune the car on a dyno. And the tune feels pretty solid anyway. The reason I'm considering the headers is that I hear a slight exhaust leak after a cold start. Not a big deal, but it bothers me. If I'm going to the trouble of digging into everything to correct it, I might as well put headers on it, because that's how I roll.
