Data log this morning. The injectors are pretty much dialed in to the manufacturers specs and the car runs well otherwise

That was the log, I want to see the tune itself.
I was going to suggest cutting the min fuel milligrams under the transient fuel tab in half. Often larger injectors will require that number to be dropped. I think stock on many calibrations is like .0410 or something like that.

5FDP mine are 36 i cut my mg to .031 or somthing from .040 and it was much better. He might benefit from this hp 12.0 is a big difference.
Also does he have the right data

Thanks guys, will post tune this afternoon. I experimented with that before, however mixed results as it did in fact lean out the idle beautiful but caused lean knocking somehow in off idle areas. I am more than willing to revisit and learn, and do it better

Which 42lb injector out of curiosity

You have not failed the MAF correctly
Airflow > Dynamic > high rpm disable > set to 8000
Engine Diagnostics > airflow > MAF Freq fail > set to 0 or 1
Get rid of your MAF channels and add injector pulsewidths
Why is your throttle voltage .06?

I will humbly and gratefully listen and follow any good advice. Throttle hangs until I stab it to return to idle. Mileage is good 20 mpg around town. I race on the 2nd. I have a 9 inch with 4.56 gears and Racetronix 340 pump. Thank you again

Also noticed your injector data is different than the Ford to GM conversion data i have. I could share it with you later on.

Observations:
Idle mixture did lean out a tad. I cut the min transient from .041 to .030 or whatnot and at first it seemed to move a half a point in the correct direction. But eventually realized it still settles at 12.2 so I may want to cut it all the way in half meaning .020 or whatnot if it doesn't affect anything else

Also, the throttle is less likely to hang when it's supposed to idle, it did it only 1 single time in the entire test drive home from work last night and to work this morning. However I still think this may be a mechanical issue meaning the throttle plate or cable or something with the sensors in the throttle body
