Nope, all #s SAE corrected. This is twice now they've given me essentially the same output.
Point being, if they're calibrated correctly, they will produce the same output (ie, the correct power of your car...).

I will see if my camera will take a decent picture so you can see it. It makes decent power down low but it just comes on way strong over 3500 to 3800 range. The HP peaks at about 6000rpm and the TQ peaks at about 4200 or so. I will see if I can post the graph. And I guess its a 222 cam but the exhaust duration is 224 so I am just calling it a 224 cam, doesnt really matter since the dyno #'s are what really count.

that would be 1/4 times that count most.. you dyno queen!!! 
) j/k 9 days till I get to dyno my car lol and tune it.
Im curious to see the curve as well, The cam should still have pulled real well down low, and they say the heads help give back alot of the low-end as well.
Though I guess if he gets any better low-end, he might just end up riding on rims haha

If you have a 220/230 cam, it is a 220 cam and not a 230 cam.
You should be proud of such numbers on a 222 cam

SSBody - What is the cam's LSA & advance?
I dunno... Mine is a 224/224 on 114+2, and my power curves are nearly identical to the LS6 cam (I had previously installed, w/ stock heads) below 4250rpm. My tq peak is now 5200rpm, and HP peak is now 6400rpm (ported 243's, .038" squish, 8.50 DCR). Will 2 degrees of intake duration & (presumably) a slight difference in LSA really cause such a huge shift in Tq-peak & HP-peak?
Hmmm... I'm happy with my output, but now am really curious (concerned?) about why the heck mine is peaking soooo high comparatively. I would totally have liked to have seen my #'s all peaking 500rpm lower....

Nice numbers!
Can anyone chime in on this - isn't the FAST 90 set up overkill in this situation? I guess my question is wouldn't he have similar results with a stock LS6 intake? I read somewhere that the FAST 90 upgrade is not worth it until you are over 500 RWHP? I am just curious!
Love to see the small cams pulling 400+

Passing the rumor potato...
I head heard that the fast set-up can rob low-end and possibly hinder hp/tq if your set-up doesn;t flow really well. It was being talked about when they were saying the 1 7/8 headers would cause loss of power as well compared to 1 3/4 headers if your system didnt flow really well.
Have no experience with either
Just if anyone remembers those topics maybe they can point ya to the right thread where they went into it.

02REDHAWK- amazing. i was on speed inc's dyno in chicago then kirks dyno in detroit(old ap-engineerein bilding) and there was a 30hp difference. i was also on hardcore motorsports dyno in flint and even that dyno was 27hp higher then the stang dyno.
CASEY02WS6-MY CAR MADE 434hp stang dyno then i daaed the x4 cam over the x3(8-10 hp)and a fast 90mm w/NK th-body. my total power went from 434hp 384tq to 463hp 413.8tq. 346ci motor under 500hp.

Not wanting to thread-hijack so I'll keep this brief - but the Mustang dyno I used was also Kirk's! He did my tuning, BTW. HUGE props to Kirk and Vector Motorsports.

Ok, here is the dyno graph. So everyone can look and see for themselves. Wow, alot of wonderment about the FAST 90/90 set up. Yea, probably alittle bit of overkill for my set-up, but who knows what way I will go in the future, so I just planned ahead and spent the money now while I had it. I ordered most of my stuff while I was in the Arabian Gulf for a year, so when I wasnt on patrol, I had some extra time to research parts and did alot of reading of the posts and threads on this site and just made a decision. And man does it look nice with the anodized fuel rail kit and braided fuel lines. Predator Z, thanks for setting me straight on the cam size. I got in touch with the Comp Cams guys and told them what I wanted to get out of a cam(power, torque, decent gas mileage, driveability,etc) and this is what we came up with and it has worked out all around so far. Also I think I got the perfect set of heads and I am sure that helped a bunch also. I was shocked at the numbers and I have to say that FAST 90/90 set up sure helped out a bit and it still get 25 MPG on the highway so I am not sorry that I got it. If I add a decent gear, the car would be more than I need for the street so mission accomplished. Now to see what it will do on the track. I cant wait.

Ok, so I guess I cant post the dyno graph because its too big or something and its bigger than the 100KB you allowed or something. I tried to shrink it too no avail so I will try again tomorrow. Sorry about that.

The heads are a set of #706's from a 5.3 LS1. The were CNC/hand ported with 2.02 and 1.58 valves and with the double valve springs and stock combustion chamber which raised my compression about a 1/2 point and no P/V issues. Not sure what the flow #'s were but judging by looks of them and the power they made, I have to say in the range of 280 to 300 on the intake side and maybe 210 or 220 on the exhaust but that is just a guess. I got them from Forcefed High Performance and they are a sponsor of this site. The were a great deal (somewhere around 1500 for the set). Compared to the stock heads that came off the car, the runners were huge.
