Well they said they dynoed the car before they started working on it. They pulled 201 at the wheels. Unfortunately he didnt tell me the torque. But the only thing I had done at that point was cut of the stock cat back and put some spintech sportsmans on that I had laying around the garage and dumped it. SO it was 201 with those mufflers. I had them install a set of BBK tuned length shorties, the UPR O/R X-pipe, and the American Thunder Flowmaster catback. Then he put it on the dyno and it layed down 242hp and 274 tq. That is a pretty significant jump at the wheels for that. Then he started tuning a little bit with the predator and got it to 249hp and 286tq at the wheels. And he could only put in so much timing and all cause I only had 87 octane in it. I dont have a cai yet but when I get one I'll have to go back in and up the WOT fuel ratio a little bit between 4k-7k.
Overall I am very pleased with the added power that just thse few mods added. He was very surprised that it was that much of a jump. He said it was the most power a GT had put down with just that little done to it. But the sound is mean, not nearly as loud as I was hoping for but it'll do.
So I would have to say, from my experience which is just from yesterday, from what the dyno says I will say these have to be pretty damn good parts and I recommend them :drink:
