Hey guys, this is my first post. I just bought a 1993.5 TT Auto. Right now it has n exhaust, downpipe, and intake on it. I was wondering how much boost a stock supra can take, and if its a good idea to knock up the boost, without doing anything else to the motor. And if so, what kind of gains should I expect? And what kind of boost controller would be good to get. Thanks for your responses.
