I recently picked up an 03 5 Speed black mustang with 49000 miles. I've done a few things nothing major. I've been waiting to find a Trust worthy shop people would suggest going to. I'd like to do gears maybe a super charger or turbo. I've already dropped in a CAI from AM and a SCT Tuner, and a Full Catless X pipe Pypes Exhaust. I've yet to install my underdrive pulley. Thats pretty much it for me. I love my car so much and treat it better than most people treat their children haha.
