Justin, im pushing 13psi in my 96gt. You have to put a wide band o2 on it with a rich lean meter. Dallas mustang tuned it the first time and they just put the meter in the end of the tail pipe wich gave a false reading and i blew the motor two weeks later. I had my new motor built at Houston perfomance. Steve is very knowledgeable on the mod motors. I have all forged internals and p&p'ed my heads and have custom blower cams. With a supercharger you really need to get a good tune done on it(chip). They set my car up to run a little on the rich side. If you have a timing adjuster then you can pull some timing out for the time being until you get a tune. If your detonating then dont get on it till you get a dyno tune done. Its ok to drive it, just stay out of the boost. Give me more details and maybe i can narrow down what your gonna need besides a tune.
