Question concerning GT350 Throttle Body tuning on 2015 Mustang GT with '18 Intake Man

[Volstang]

I have a 2015 Mustang GT auto with an '18 Intake Manifold (ported) and picked up a GT350 Throttle Body cheap and although I know it wouldn't make much extra power, I wanted to play with it and tune it. It have it running well. It idles and drives fine but I still get ETC Angle error that I can't seem to tune out in the WOT section of the ETC Angle Error log. I've used The Tuning School methodology for tuning the TB and it has worked well for the most part but can't seem to get the errors down below -6. The car runs and drives fine but I want to get the angle errors down as much as possible. Adding tune and logs for review and suggestions. Thanks for any support.
