Adjust the PE settings so you aren't staying in closed loop under boost. It happened in both of the logs. You are well over 110-120kpa but it's still in closed loop and the computer is yanking 20% worth of fuel with the trims.
Raise the PE kpa up to 90kpa and lower the pedal enable back down. Maybe like 40-50%.

latest log, I think I over shot my fueling.Tahoe2-22-2.hpl
Hard to say, your wideband is not reading right in the logs. It's always lean and it's stuck at 1.36 lambda while idling.
The trims seem okay but under boost I can't tell because the wideband isn't working, in the logs at least.

I think I bought the wrong wideband I bought an x series AEM and I've read it will only work on a can bus
It still works you just have to use another method to read it.
If you have the PRO interface it will wire straight into that. The standard interface needs to use a 5v reference circuit on the computer, then you wire the wideband to that and create a custom channel. Most use the EGR circuit. You can google and youtube how to do the EGR wideband with hp tuners to find all the info.

I'll look that up, its a portable wideband I wired up the tahoe has an innovative. I'm not using the pro I am using the prolink with a pro upgrade

It's close at time and richer than commanded at times, easy enough to work out if you created a lambda error or AFR error against the commanded AFR.
It would tell you exactly where it's rich or lean of the commanded and by how much %. Then that amount can be special copy/paste by half into the VE table to smooth out the fueling. Smooth with the special function and hand smooth the table after each change. Shouldn't take but a few drives to dial to whole thing in.

its a learning curve for sure.
I think I setup an AFR error using afr math the chart contains rpm and maf to compare to
