Are you dropping boost, or maybe spiking before you level out? WHP dives towards redline, no reason it shouldn't be climbing all the way to redline with your setup.

I think I may be spiking out, boost gauge reads 7psi until I shift gears. The car seems to rev fine til 7000rpms then bogs a little bit, I am still under the learning phase of tuning.

Your fuel tune definitely needs work. I think your drop-off in HP is coming from going super-rich at the end (below 10:1). I'm home now. Let's try to get together and get that fuel sorted out. It's darn easy.
That said, torque is looking good for 7psi (170 ft-lbs). Your HP will pick right up when we level out your AFR.

That was my main thought. The AFR does look a bit wobbly and where my HP drops is right when I get rich as you stated.
Car pulls very well, I will give you a shot in the drivers seat if you're interested. You don't notice any power loss after 5k when driving, but maybe I will notice a change once a few tables are fixed. Your house is right down the road from my work, I will swing by when you're available one night or even this weekend.

I'm probably the worst MS tuner on here so for gods sake don't copy my stuff cause who knows if its right, Ive just copied other peoples stuff and tweaked it to my car. Anyways with that said I noticed a couple things with your tables. Your afr table only goes to 100kpa (roughly 0 boost) and ramps like crazy (12.5@70kpa across the board), at this rate you'll be running 12.5 cruising on the highway and low 13s at idle. Anyways, heres what my tables look like, (me on top) and heres a good thread to check out for afr tables.
For the second picture I'm comparing the fueling tables in 3d view, you can kinda see how yours looks like a canyon, the areas you've autotuned are ok but if you ever step out of a tuned area your gonna have crazy amounts of fuel
Hopefully this helps some. I dont know, hopefully somebody else can fill in with more technical knowledge on what I'm getting at.
EDIT:
Just out of curiosity do you have the .msl you used to make your virtual dyno?
