My 05 LS2 made 384/392 on a Mustang with ported stock IM and headers. Made 468/445 by adding FAST 102, CNC'd stock heads and mild cam. Same car made 485/440 on a Dynojet. This all done in S Florida in August, so numbers may be higher when the weather cools off a bit.
I would be very surprised if this build made similar numbers on another dyno. It can be done, ask HC Mechanic. He made 525 rwhp in a max effort build in stock ported heads. Leavin U is also above 500 rwhp on stock heads.

Your numbers are quite realistic.

Mustang dynos are generally very stingy. Maybe the OP has done this type of work and didn't leave enough detail in the original post.
I edited my previous post to make it more clear what I was getting at. Sorry for any confusion.

I was posting my numbers only as a comparison. My point is that the OP's original numbers seem very high for CAI and headers only, especially for an LS2 on a Mustang dyno. In addition, I am surprised that adding LS3 heads and a cam would add over 100 rwhp to the wheels. Not unless it was a max effort cam, raising CR (whick wod definately require flycutting the pistons), an UD pulley and any other tricks.

I agree that over 100rwhp is impressive gains, but you have to remember that when he dynod 404rwhp he didn't even have a dynotune, it was only a tune from a predator programmer.
100rwhp is believable for a good head/cam/intake/tune....far more so than 404rwhp with intake/headers/programmer.

My 06 Z51 with a Spin ported Fast & TB only will do 355 RW on a calibrated Mustang dyno. I never dyno'd the car stock, if we assume 0 gains from Spins then taken19 #'s on a Mustang seem plausible.
If a Spin ported Fast & TB are worth anything then I wonder about both Mustang's reported in this thread.
It really does not matter as gains & loses are really what matters. Dyne's are like politicians, tell me what I want to hear & your in!
