Well, I guess my info was correct;-) It looks like you do have fuel issues. 
You could probably benefit from something similar to my enhanced fuel delivery 
system for the high end. I also recently opened up my air delivery with a MAF 
bypass. I used the recirculating breather pipe on the turbo intake, not used 
with the dump can, to hook up a small air cleaner. This allowed me to go to 
over 30 lbs of boost without MAF cut. I figure that you could do something 
similar and lean out that fuel curve some. 

As I look at my dyno runs, my torque is coming on at a much lower rpm. On the 
most recent run of 2 weeks ago, my torque peaked at 475ft/lbs at 4400rpm vs 
your 5600rpm and hp peaked at 420hp at 5600rpm vs your 6400rpm. My previous 
best was 430ft/lbs at 4700rpmand 414hp at 5800rpm but that was before the 
enhanced fuel system, MAF bypass, custom tuning and bigger rear exhaust. On those 
earlier runs I also had your same rich dip and then it settles at 12.5 and 
continues out to the end. When I was in California last year at sea level My dyno 
runs looked exactly like yours with the mixture continuing up onto lean to the 
end. That required me to back off my boost to about 22lbs to prevent running 
too lean at the track. 

I think there is also some very valuable turbo sizing information from these 
graphs. On my recent runs I am running out of air as my horse power falls off 
at the end. That really supports my going to a tubular manifold and larger 
turbo with ball bearings;-) If memory serves you're running a T-60 nonball 
bearing on the Green Beast(GB). Even with the tubular manifold and generic tuning it 
looks a little large or laggy for your purposes. I know you've already got 
some Killah Turbo(KT) hidden somewhere in your collection so the rest of us 
await the next iteration of your work in progress on the GB.
