Trent it defueled just the same with your tweaks. 
Ill send you some logs in a bit.

Ben have you considered switching to LB7 electronics and swapping heads/injectors?

Ya send me a log , Also a tcm tune thats in the truck right now , that hasto be in sync with whats in the ECM to a certain extent .
NO!!!
As annoying as this is, I dont want to deal with LB7 injector$ at all!!
And I want to keep the variable vane turbo.
LBZ Swap ? When did you put the VVT back? I thought both of the twins where fixed?

LBZ Swap
no my twins have always used the vvt as the small turbo. I like being able to use it as a turbo brake for towing, and to warm the engine up faster in the winter.
Ben, have you tried a different OS, just for kicks try *****1668 04 LLY converted to a dsp.
Ben will have to change the pulse for his truck , he has 30% over injectors .
GMC_2002_Dmax
The Still Master
I suggested that a while ago, I ran into a issue with an LLY that would limit MM3 to 88 and would not fuel over that.
I swapped tunes from another LLY with the same OS, same segments and problem solved.
It is either a corrupt ECM, corrupt OS or a tuning issue.
If you need help Ben my offer still stands.
I am going to bump this up Ben , I never did see a log from the tune i made changes in ? I guess its not a big priority to get it fixed ? The changes made took 5 minutes and was just a "test" to see how it changed the issue .
and i have since found a few more changes that I am pretty certain will do the trick when it defuels at around 89 mph . And emailed that tune back over along with another non dsp test tune that has your pulse and timing tables in it.

This morning I launched my offroad beetle into the air sideways at 45mph and rolled it 6 times down the road and then into a ditch. Im pretty sore right now and have a headache...so fixing my truck isnt really a priority as of right now.
ben
damn ... I hope your ok Ben
Nope
I have a few things for you to try , email coming your way .
Sorry to hear that Ben...Hope you're ok...
Trent I tried your base torque and torque limited tables and it seems to be better. But it shifts badly at part throttle, and you can see in the logs the main rate is still jumping all over the place. (only the defuel isnt actually felt because of the tliq and base torque tables)
The weird thing though is initially it defueled just the same with trents modified torque-table tune. Then I reflashed it to a stock LBZ-airbox calibration with the Tech 2, then re-full-flashed my tune back in and thats when it started acting not as goofy anymore.
Another odd thing is trent's base torque tables and tliq tables were similar to some of my very old tunes (like from back in 06 when I had a stock LLY motor and BD turbo and raced it all the time) yet they only defueled sometimes...
So from what I can see, somewhere along the line maybe something outside of efilive's capability got screwed up in the ECM.
If I do an extended WOT run, it still throws MAF codes (and subsequently does odd fueling things) with the new MAF calibration that Trent helped me out with, so I still have some messing around to do with that. Even with the "out of range" enablers set way high it still throws P0101 and P0103.
You cant set those codes to "not report no mil" on an LLY (from what I have found) because that causes other weird issues and 'phantom' codes. For example if you set P0101 and P0103 to not report, you will be driving along, doing some WOT runs and all of a sudden you notice the truck just doesnt feel "right"...not as punchy as it normally is. Check for current or pending DTC's and there are none. But if you tell it to "clear codes" anyways, you suddenly regain the "normal" feeling in the truck. I had this happen a lot back in 06 when I first started racing my truck, so before each run I would clear all codes with the Tech 2 (didnt always work with efilive, sometimes it would still stay in the "phantom code" mode) and didnt really have as many problems.

basically, the tech 2 reflash seemed to have a huge effect on this issue; an efilive full-flash didnt do anything.
