if u want ur car tuned right, the guy to go to is mike dez @ dez racing, his customer service is absolutley the best, he will not let ur car leave til he feels it safe to go, and what puts him a head of alot of tuners is that he has gone to all the ford computer training seminars ford offers, because he used to work for Tasca ford i do believe. So he knows how to read and understand everything that the computer is doing, also he sits in the car and tunes with his laptop which is pretty cool. i've tried ACS racing they are decent but way over priced and they are shady people. Just my two cents!!! hope i could help.
dont go to cd performance. i just had a supercharger put on my gt. the juicy that runs the place jerked me around sooooo hard, busted my a/c line, and the car didnt run right since. how is ne dyno??? i heard they do programming for svt.
