The O2s and the trims both are incredibly slow. What's the exhaust setup on it? Headers, manifolds, etc. and how far are the O2 sensors from the cylinder head?

I don't see anything abbie normal in any of the data logs. Do you have a log capturing the event you're talking about? The "Bank 1 goes crazy lean"?
Cool lookin wagon.
Has a data log of the event been posted? Time stamp?
You shouldn't have to convince him of anything. It's up to him to diagnose and repair it. That's part of being a tuner. If he's throwing his hands up and walking away, so should you.

This. Precisely.
Sounds like you need to pay someone who knows what they're doing. I can be contacted directly through the email in my sig.
I email tune everyday. If you're interested you can contact me through the email in my sig.
OMG that has nothing to do with it. I can understand how you'd think so though. All that means, the criteria to set P0335, is that if it's in speed density, with the P0103 code set, under the same...
I don't know that. All I know is it's not setup correctly which means it's running off the MAF. Whether the MAF is dialed in correctly or not, I have no idea. But setting the MAF fail Hz to 1 or zero...

The MAF fail hz is only part of the process. You have to set the DTCs up correctly. They way yours are setup, it's keeping it from going into speed density. It HAS to set a P0103 code for it to go...
P0102/103 are set to no error reported. That prevents it from going into speed density. I don't care how many trucks he's done.
If you need to explain this to your tooner, you need a new tooner.

Codes not setup correctly to actually fail the maf. ^^^^
It looks like tuner guy wants to have it in speed density but it's not properly setup, so it's running off the MAF.
The interruption in crankshaft speed caused by the cough/pop/banging is what's causing the DTC. Fix that and the code should go away. With no data log or tune file to look at all anyone can do is...
Fuel trims are working. You're logging way too many pids. Need to cut out 75% of them at least.
What problem are you trying to solve? Where in the data log do you perceive a problem? If it feels like it's down on power, where in the data log were you doing a WOT pull?
Why do you have your...

OMG I been throwing them things out for the longest time now. Think I'm gonna go cry now. Thanks a lot! LOL
Why you gonna bump a year old thread just to be an ass to someone?
Looks like you have at least 1 problem cylinder on bank 1. And if you hear pinging, that's not good.
Could be an issue causing the popping and banging and that's what's causing the P0335 code. In other words, the code is a symptom, not the cause. Of course this is just a guess as that's what my...
