I just took the car out for a short drive 5.3 small cam turbo. I have attached the tune and scan. Let me know what you see thanks.Attachment 88613Attachment 88614

Since no one more experienced has responded, I'll take a stab at it - it looks like you're using the narrowband O2 sensors and they appear to be reading a bit lean though without wideband its hard to tell. It also looks like under low rpm moderate load you're getting some detonation. If it were my vehicle I'd probably up fueling by 20% across the board and reduce mid range spark (starting at 1000rpm - .28g until the big block of 10 degree cells) by 20% and re-log.
What MAP sensor do you have. The linear and offset numbers look strange. That can throw off your fueling. I would make your PE rpm delay to 0. GOT TO get a wideband on that turbo beast.
There is a wide band AEM through the egr. On the second line set in red with a wide band error.
Hey Shock,
Could you upload the layout you're using for your logging?
Thanks
Attachment 88701 here is the latest scan
Has the 3bar GM sensor
I don't think those are the correct numbers for the GM sensor.
Its still looking super lean to me
many things are wrong.
what injectors and fuel system?
the MAP data is wrong. 312.50KPA -11.25KPA
your VE numbers are so small hence you have no spark resolution
you have no PE on transition into BE
