P0101 after larger throttle body install

The fuel trims are not problematic at all. So probably something happened before this freezeframe thing.

I'm not positive but I'd think if the fuel trims were the issue it would be throwing a fuel code. From what I have researched the p0101 can be for 10% variance in expected mass air flow values. Is that correct?

That is a possible reason for the code to be set. Try adjusting the MAF minimum/maximum dag values(Not the MAF curve). I don't remember the exact names. There are 2 of them with small values. If I remember 1 of them is positive, the other is negative. There are 2 more, that are multipliers. I believe they were set to 130. Try adjusting them and see what happens. I don't have my tuning laptop to look up the specific names. hopefully you can find them.

I see MAF flow delta absolute high and low thresholds which I think is what you are referring to. They are .7936 and -.7936. do you have a recommendation on how far to bump those? .80 and .-80?

I'd change it by 10 to 15%..
