Wants to die shifting from drive to reverse

[Bum454ss]

5.3 LM7 swap in to c10.

I've been working remotely with a tuner and I think it has been going well. Can't seem to figure out a condition where the truck wants to die when shifting from drive to reverse. It has a rough idle in reverse under the same conditions.
But when shifting from park to reverse everything is fine. Idling is fine in reverse. It's only one drawing from drive back up through neutral to reverse that it wants to die out. Wondering if someone might take a look at this file and log and offer some insight potentially? I do not have a wide band gauge.

There are a few things going on any competent tuner would quickly recognize.

1, the VE is complete garbage. Anyone who think that's what a VE should look like doesn't know what they're doing.

2, the IAC is way too high. Again, basic stuff any competent tuner should quickly pick up on.

3, you aren't logging any idle airflow pids that would help you diagnose the problem and dial in the IAC counts.

4, the injectors aren't stock so without knowing exactly what they are, it's impossible to know if they're setup correctly. If the injector data is off, everything else is off.

I'm stunned. Not sure how our initial communication got dropped but here I am $350 to the wind. It's running and driving. But that's it.

Here's a new log with different pids that I actually believe you sent me a previous channel configuration for.

If that was directed at me, after I quoted you a price you told me you were going to give it one more shot on your own.

Your tune and even your channel config says your $350 guy doesn't know what he's doing. I know I sound harsh but it's the truth.

I appreciate your candor and refreshing my memory. I'd love to start making some progress.

Sent you an email Matt.

Not even close. Already seen 2 this year that looked like Tetris got in a wreck with Qbert.
