I just put in a ts ecu for crawford plenum, stillen cat-back, z-tube in my 2003.5 sedan 6mt yesterday. it seems to have woken up the car. its a lot more lively now. i can feel the stronger pulling. it also seems to rev a little faster. i would say that it was well worth it. i happened to take a business trip done to LA and walked into technosquare with my ecu in hand. took about an hour.
