This is good as gold to me right now

. A great place to start. I owe you lunch or a beer or something.
Thanks Brian. Will be posting a data log very soon.

Glad I could help.

"AMUU was superseded to ASDX". best to start with the latest factory update...

Try this for a starter bin ..stock ASDX bin, with a modified timing table and patches applied (spark/bpw in data stream),egr/hiway cruise are disabled..

Burnt the chip that CFI Z51 uploaded (stock ASDX bin, with a modified timing table and patches applied), loaded it into the zif modded 7747, did some data logging. Man what a difference, both log AND feel where as different as night and day. Now I have run a second data log, dumped it into the Excel worksheet and am going to burn the chip/log again.
My questions are these.

Do I use the averaged corrected BLM table or the non_averaged?
What patches, if any, do I remove after the tuning is where I want it?
Do I enable Highway/EGR when I'm done?

Thanks for the assist in advance. I will upload the final modded bin for comments when it's done. (Also thinking about making a tutorial with pic's for the complete noob such as myself, from beginning to end with the steps I took to get to the final product.)

Not sure if this will help you but i had much better tuning success zeroing out ve2 table and adding it to ve1 table. Not everyone does this but there are some great posts here explaining this.
