Ok, I see DOD is disabled in B0921.
Some thing is wrong with VE table B0200.
HO/LO spark timing tables do not have sufficient advance.

what would you recommend I do to correct the issue and could this be cause by the end not being updated by the dealer?
Do you have the stock tune file from your vehicle (or one exactly like it)...?
That is the stock tune, only turned off DoD.
I named it Mod so I wouldn't mistakenly modify my stock tune and not have a reference point to restart from.
Stock tune VE table is not right.
Are you running MAF...?

It has a MAF but I haven't changed anything in any of the tables except DoD turned off.
It would seem I need a stock 2006 Trailblazer/Envoy 5.3L tune to get this thing right. Anyone know where I can find one since I can't seem to locate the Holden Tune Repository?
I just found the Drop Box from our good members here, I'll go through the tunes and see if one matches up.
Well that wasn't helpful as I thought it would be. The tune on file has the same OS and calibration that I have in my wifes truck. Anywhere else I can look for a stock tune for this engine that may be updated a little more than this one is?
