New dyno #'s with LE2 heads

New dyno #'s with LE2 heads First off this is on the stock 99K mile bottom end, stock waterpump, and heavy 17x11's with 315's with 26psi in the tires so its not a dyno queen. I'm still having the problem at 5800 RPM's. 
I'm starting to think its ignition related, any ideas? Other than that the car ran great on the dyno, the baseline was 391rwhp so I gained 14rwhp. 
I'm going to the track tomarrow so keep an eye out for that thread with track #'s. 
Anyway here's the graph.

30rwhp gain with the heads. I wonder what it'll put down once I fix the topend problem.
Here's video of a few runs.

Well for starters here's a car dyno'd with a stock tune and the Tq curve seems to hold alittle more of a line. I am not trying to be rude or **** you off, just simply saying i wouldnt be happy with the tune. Your number should start off close very close to your peak and them slowly fall, instead your tq curve is flat then jumps to make a peak number and falls again.

1/16th preload, and there is no miss, and the MAF reading goes crazy at 5800+ so that leads me to think it is valve float.
