I've also had this kit on for 9 months and 10,000+ miles...ohh yeah and without a proper tune that I had paid for to begin with.

I've waved the STS flag and tried to hold my tongue on all the issues I have had with the kit. Mainly because I had the first AT7. If I can find an UpRev tuner and get this tuned I might come back to there side. As of now I'm about a 1/2 second away from ripping out this system, which when changing the oil is a royal pain i the asz to get to the oil filter, and going back to a stock set up. Now with the 100+ heat I can drive my car about 15 miles before it tries to overheat. DONE!
