Dude your getting confused...re-read the thread.
This is my point, my car tossed down 363/361 at 3300. You should be concerned. Yes I agree that if my car was dyno'd with a higher weight (like yours) my numbers would be even higher.
Between your car and mine and their respective set-ups (your monster cam, ls6 and stage 2 heads + a tune !) your HP is LOW (for the set up) and your torque is flat on the floor.
Sorry dude....if you see a Black FRC floating around on W.W. catch me at a light and I'll prove it to you.

Get the facts strait. You also said APE put your weight in @ 3600.

Stock suspension sucks! I also got really low torque numbers on a Mustang Dyno. With the mods in sig I put down 346 hp and 329.8 tq? Doesnt sound right at all but hey. Runs better, and I'm tired of messing with it for at least another week
Guys...... i gave a call to the tech people at Mustang dyno and they confirmed that 500 lbs either way might make a couple of hp or lb ft diffrence but that is all. So if we told the dyno it weighed 3000 or 4000 it would be 2-3 hp off.

I think the problem is your cam! Get a single pattern cam and I think you will see your numbers improve! You want torque go to a smaller cam. Check this guy out: https://ls1tech.com/forums/generation-iii-internal-engine/167220-flow-s-local-mildly-ported-heads.html

Well, now that I think about it, the TQ is where it should be with this cam. I want to add nitrous in the future so I think a reverse split would be better for that right?

Somebody has to be able to help with why your torque is in the pooper....I was looking at the TEA 5.3 heads and am second guessing myself.

Isn't the Z06 the lightest C5? Thinner glass,Ti exhaust,etc.
Yes ,the Z06 is a notchback design but the Z06 and FRC are different models according to GM.

Oh well, that sucks, doesn't matter tho, ls6 stage 2's and 231/237 will be in my future

Bottom line is they look inline for the mods posted IMHO.

Put it on a dynojet to see what your numbers really are. I wouldn't put to much faith in your current numbers. Also don't mention your current numbers and have it retuned and you'll probably be pleasantly suprised.
If its not a good tune steve, ill retune it for free. Let me know what it runs at the track first. 
On my dyno, a 397 rwhp 3600 lb car will run 11.6@119 . A 475 rwhp 3200 lb car went 128 mph. My dyno is pretty stingy but we use the dyno for what its made for: to give the customer more hp, more tourque and better drivability than what he/she came in with. Is that the tune you recieved steve ?
MIRECK- I want to invite you to make a couple of pulls free of charge to show what your car makes on our mustang dyno. Interested ?
