I sure hope my Monster 3 clutch with only 1000 miles on it isn't slipping at these power levels. But what i don't understand is why my horsepower still maintains an incline while my torque is flat lining. If my clutch was slipping wouldn't it be shown in the horsepower?

so, if torque stays the same and rpm increases then the hp keeps going up.

I think youre on par with the hp numbers, not low at all IMO. Dont forget that dyno is a tuning tool..
About the torq though, something is wrong with the curve!
FYI, I did 404rwhp on a dynojet with a tad smaller cam, but with ported FAST 92/TB and stage 3 243s.. and my car is tad faster than a Nissan GTR

Do you guys think it could be something valvetrain related? Ex. Inncorrect pushrod length, wipe pattern? I would think that if something valvetrain related was screwed up, that it would be affecting my horsepower numbers. Also another thing that I thought of was the new ypipe I put on which is 2.5 inch. Other then that I am stumbled. Monster also told me that my Dynograph isn't showing signs of clutch slippage in any way.

Whatever; that's what clutch slip looks like on my dynojet... I'm not saying it's definitely YOUR problem, but that's definitely what it LOOKS like.

I would have liked to see a little bit more from that setup, especially the torque.
I'm running the same setup - PRC LS6, 228/230, LS6 intake/Ported TB, UD Pulley, M6, etc. I'll be dyno'ing my setup in a couple of months. I'd like to squeeze out a little more torque at least.

I can post up dynos of what clutch slippage looks like and this doesn't appear to be it. There is usually a drastic drop in torque, the torque usually doesn't look like a plateau when the clutch is slipping.
I'll pull up some dyno sheets from our performance shop (SNL Performance) and will post them on here if you like.
Regardless, OP needs to call the shop and we'll go over a few things.

The hp isn't bad but the tq is way low. I hope you guys figure out the problem, I have no helpful suggestions for this one

looks to me like the cam is either installed a tooth retard or ground wrong from the cam manufacture..... the reason i say this is because i have seen it before... when you retard the cam the power suffer down low and in the midrange, but carry better up top at times..... but with the plastic manifolds out right now, and their given runner length they cant carry the way it should..... so you get a soggy lowend, mid-range car, with no more top end then a proper setup.... i have tuned the cam many times and they make very good torque

Does seem low to tell you the turth I just don't like those cam numbers but I think it could be a little sequeze out of the Tune
I done a car with a little less head
Ls6 intake 232 236 600 600 111, stage 1 ls6 prc,
With a eps tune 437 419

It does look like at least one form of clutch slip. I'm only replying because I was asked. This graph is about 5 hp and 5 tq off of the original poster's results... other than that they look pretty similar. This is new-ish clutch that was slipping on our Dynojet not that long ago:
OP's graph for comparison:
