Seems low to me. I would guess about 400rwhp. What was your hp before? Did you do all the mods at once or heads last?

Yeah, that sounds low. Even without a ported tb and UD pulley, you should be around 400rwhp with that cam and heads in an 02 manual with the stock gears on a dynojet. Actually, with the ported TB, UD pulley, and a cutout, I'd expect close to 400rwhp out of the 224 cam in such a car.

Where does the cam peak? Maybe it's off just enough that you're peaking at something like 5400RPM.

Flowmaster exhaust? Cutout?

Dyno it again with the cutout open, but even if you hit 400, you're still down a good 15-20HP.

What does it run at the track?

I haven't ran it yet, the guy I bought if off of in SF said it hit 12.8 but that's just what he told me. I'm just wondering where that 20-30 HP went?

I'm running close to the same set up that you have.
Comp 224-228, 581-581 on a 114, Patriot stage 2 ls1 heads, SLP long tubes, Flowmaster exhaust and made 392rwhp. No cutout, no ud pulley, and with high flow cats. This is on my 2000 m6 T/A with stock rear and stock gear.
