On this board you will be timed out so do long posts in notepad and paste it in the message.
OK. On the def files by Tod. He has hundreds of hours in reverse engineering the GM calibration code. It has several HUNDRED different calibration points. I have the GM listing in english of the calibration but both of us are rather guarded in release of the information. I would email Tod directly about his TDFs. He might point you to specific points you are looking for.
Tuning software for OBD I
In addition to Tunercat:

there is Tunerpro:

Moats stuff is here:

I know there are several commercial systems out there but they are beyond my pocketbook.

The iginition side of the tuning software is pretty straightforward but there are some real gotchas in the fuel side due to the way the calibration handles the fuel for the dual injectors.

Unless you are a real glutton for work the stock system is more than able to contend with normal to modded motors.
