I am going to help you all out here.
There is a conversions table in EFI-Live, it is a folder and it is clear as day, it is above the information, top right of the screen.
You can use this table to import a fueling table, timing table, torque table and then play around with the values without screwing the real table. Then when you have the values where you want them you can copy it back into the real table.
This is also important for adding or subtracting values from two different tables, two tables that you might not think you can compare you can even if they are different tables in the tune files.
If you alter throttle based injection quantity it will screw up torque limited injection quantity, this is a fact, if you alter base torque it can alter the de-fuel on the shifts.
If you have a huge disparity in the main injection pulse width tables from mm3 row or in adjoining cells and you follow the de-fuel with the scan tool link you can see where you may have to add or take away pulse width to correct a bad de-fuel or a over fuel on a shift.
Most people make the mistake of altering the throttle table first to get more fuel without altering the main injection pulse tables, if you go down that path you might someday get a good shifting tune, you may never, but that table is the key to everything else in the tune, that tells the ecm where to look, that and fuel pressure base on the LB7/LLY ecms. That is your right foot asking the truck to do something and it responds by looking up fuel MM3 and from there all other tables link for timing, pilot timing, pilot pulse, etc.
As far as the transmission,
When you alter the tq values in the TCM you have now upset the request for a proper de-fuel, when the request is wrong you now have two problems you will be chasing. one is an incorrect request for de-fuel if you eliminate it in the tune or raise it up the defuel will never be correct, two is you may have removed some of or all of the ability for the transmission to make a clean shift without tying up three clutches at once.
The shifting is by far the most difficult aspect of tuning, it took me almost a year to figure out how it all works, now I spend very little time on it because it's easy for me to fix it.
