With the same programming as before plus 20% bigger injector nozzles I'm seeing 50psi of boost compared to 27 with the stock turbo and stock injectors. With more fuel from the 20% bigger injector my max EGT's are now are 1600 degrees compared to 1800 degrees with the stock turbo and injectors. Now the truck feels as fast if not faster than it was on nitrous.
Almost double the boost and lower EGT's. 
That is just totally awesome. Let us know what that thing runs in the 1/4.
Congrats on getting in 4 wheeler magazine also.

Could you let us know your opinions on both the LB7 and LLY as far as programmers and other bolt-ons go? I'd like to get a Duramax in the near future, but not sure if I could "afford" an LLY.

I don't have an LLY and don't follow them too closely but they seem to be 50-75 rwhp behind the LB7 right now with intake, exhaust and programming mods (tuner/box stacked) but in time the LLY should catch up.
For the LB7 Duramax the Edge juice w/attitude for $800 is the best plug in box with 60-150rwhp. The attidude allows you to change power levels on the go and also has built in gauges and the ability to do 1/4 mile and 0-60 testing.
The Quadzilla Stealth for $700 has 10 tunes from 50-215 rwhp is the best tuner for the LB7. The Stealth also raises the factory rev limit from 3200 rpm to 4500 rpm in the big HP programs, corrects tire size and gear ratio changes, removes the top speed limiter, and clears/erases codes/SES lights.
