Doesn't look like you have a full Maestro map. Boost is limited to 25psi if you don't have the full Maestro suite. Also interesting that timing looks to be tapered in below boost onset and then ramped back up again.
Both logs look to be pretty equal on timing up to 6k RPM. The log with corrections doesn't look great up top. Nothing looks out of place in the log that would have effected the timing that negatively. Could have been a bump or something else. Others will hopefully chime in if they see something.

The is20 adjustable “non maestro” is limited to 24 psi peak? Regardless of slider position.
The file is looking for tq targets instead?

Got it. Those limits seem a bit lower than the limits I have seen on the IS20 base Maestro file. This is an IS38 R file though.
Or are you talking the tq limit of the file? Thinking back to the run with corrections it's definitely possible I hit a bump. I know the clean one was a smooth road for sure.
But if I'm hitting the tq limit of the file then it doesn't really matter what changes I make anyway...

This is a standard ED file?
The wastegate behavior is all over the map. no offense but this car can't feel good at WOT.
Torque Limit:
Your wastegate:
This is the wastegate behavior of my car as a reference, and i'll actually get it a bit smoother when i dial in at my final boost level:
No offense taken at all. Thank you for the help! Yes it is the standard stage 1.5 adjustable file. That is all that is done to the car. Is it just that a car without a downpipe can't hit 25psi+? Or is it just since I'm hitting the tq limit and that's the file's way of adjusting? I just reflashed the file and took it down to 24psi from 28. Set octane to 93. Will relog and see if the behavior changes.

The limits are ultimately defined in the file, not by the sliders. The sliders allow you to adjust up to the limit.
Your boost limit in those logs was 25.6psi, if you had the sliders at 28, than 25.6 is the limit for that file.
This seems sensible to me, you still have a stock cat which doesn't flow very well, and you're putting a lot more heat into it than was intended.
The boost target was reduced at the point of the TQ limit, but raised back to 25.6 after the calculated TQ moved away from the limit.
I was able to get two more logs at 24psi/93 octane settings after reflashing. Here they are:

I'm confident the corrections in the first run are from a bump because it was the same stretch of road as the file that had corrections yesterday.
Let me know your thoughts.

So it sounds like the torque limit of the file is causing the wastegate problem as well as the boost target vs. actual difference? Is that right? I'm unsure of what to do from here. Is this just par for the course on the standard adjustable file? Or do I need to talk to Chris? Should I flash back to stock and log to ensure there are no hardware problems? Sorry for all the questions.

You need Maestro so you can raise the torque target. Or be happy with this power level. It's not a "problem" IMO, the WG is doing it's job. It could be smoother, yeah.
Might also try a bit less E85.

Ultimately, this is what it comes down to.
Also need a downpipe if you want to play at high boost levels safely...then you can raise the boost a bit and go from there.
You're at the limit of the tune, which is put in place to protect you from melting your stock cat.

Yeah Maestro is going to be the sweetspot. IF I had fairly convenient access to e85, I have Sam dial me in a e30-e40 tune, call it a day. But I dont. I got 1 station that is smack in middle of Portland *traffic blows* so F that. But least I can grab my gas can fill it up, run 2.5 gal of e85 dial my timing up a lil and hopefully be around 300 ish whp. Then I can mess with the slider when im making trips out of town on pump.
