Excellent numbers. The curve looks good too, nice and steep up to 5500 and flat up top. Looks like it would keep making over 450hp past the cut-off too. That's damn impressive. Your truck should pull like a bitch, especially with a 3600 stall!
I take it from those cam specs you don't have VVT? Doesn't look like you need it either, with that kind of torque curve. What kind of cam is it, and what are the lift and LSA specs, if you don't mind sharing them?
Also, I've been trying to find out what AFR to shoot for on my 6.2, so I'm going to try 12.8-12.9 now, since that looks like it works for you.
Please let us now how the truck runs.

its a custom cam grinded by bullet 230-242 .600.600 on a 110 lsa as u can see where it flat lines out is where the intake just doesnt want to flow any more air. and my injectors maxed out right about that time. so ill be in the market for a FAST ls7 manifold and some 42's soon and try and shoot for 480-500

That sucker must sound pretty nasty with that duration and a 110 LSA. That's where the torque comes from though. Keep us posted on the intake/injector upgrade. Maybe try the injectors first to see if that's why it's flatlining. Someone had a thread on here the other day that FAST is soon going to release a Truck L92 intake. I would check that out too.
