Thanks I will give it a shot and see what happens.
Still can understand why it was fueling fine then did an adjustment to the trans 3-4 shift and took some timing out of #3 and now this is happening.

I think something has gotten corrupted maybe something the ECU is seeing when its running. I don't know. I flashed the old tune back in after I started seeing the fueling problem. It is doing the same thing and now limiting fuel. My old data log files clearly show full fueling. I'm stumped.
One thing I noticed that is odd is your boot sensor table. Why do you have it like this?

Still no luck getting full fueling. Does anyone have a stock 11352409 48re Auto OS someone is willing to share. Searching this issue has led me to others having this similar problem with with some 602 OS's and auto trans. I have found 409 manuals but no autos. Thanks in advance for the help.
Could you send them to nm2769@gmail.com
Thanks

409 OS solved my issue. Thanks guys for the input and support.
Could you email me or message me those slides pertaining to fueling/timing states? I'll happily pay for them if necessary. Having my own issues with defueling
