Well, it probably really don't, but in the words of Tim The Tool Man Taylor "MORE POWER" Ha! To be honest I really haven’t driven it much, it has less than 1K on it, I did just order a Sprint Booster for it. I've been driving my '04 coupe that I have on lease trying to get miles on it, it only has 29K on it and it goes back in July and the lease is for 45K. I'm gonna hate giving them back about 8 or 9K. I was just testing the waters on any advice on ECU upgrades from the SRT6 guys.
