I just got off the phone with the tune shop. On a mustang dyno 421rwhp with the prc 2.5, 5.3l heads with the ms3 cam. This is with new cats and a flowmaster cat back exhuast and an ls1 intake. Any ideas for more bolt ons. Installed are maf and lid, pacesetter headers with catted y-pipe. I do plan on punching out the cats.

Very nice. I have the same setup sitting in my room...cant wait to install. Get you a Fast 90/90 setup and a pulley. Should free up a good bit of hp. What kind of tq numbers did you make?

I'll find out Wed. when I get the car. It was exciting because they where running it on the dyno with me on the phone. We never talked about the tq numbers. I am planning on a cut out and punching out the cats. Definetly a fast intake.

Throw a cutout on that bad boy, we watched a customers car gain 25rwhp from going cutout over the Flowmaster muffler.

Great number. Go with the cutout and pulley first, since they are the cheapest and easiest. Then think about a 90/90 setup and your car will be one badass machine.

cutout and a 90/90 would probably show some huge gains

Mustang dynos can be set to dynojet equivalent ,something to keep in mind. Those numbers sound high for stock intake and no pulley. They sound dynojet equivalent maybe.
