23 Explorer boost drops up top

[turbogt46]

Whats up all?

Ive been trying to push my explorer and have got great results. But for some reason, I cant keep boost up top. I have 20-21 psi peak and hold it until about 4200 rpm then comes down to 19 until 4700 rpm. It keeps going down after that. I keep hearing that people keep 20 psi at 6000 rpm but Im only at 15 psi at 6000 rpm. Actual air load is at 1.82, desired air load at 2.22, actual torque at 323, desired torque and etc requested at 444, but my tip actual and desired are both at 197 kpa and dropping. All sources logged and all are not being limited. Also fuel rail pressure actual and demanded are always on track. It seems that TIP is the only thing holding me back.

Ive read that going through the SD stuff is the way to increase tip but have not been very successful. Any tips from anyone?

The log attached does not have rail pressure as I forgot to log it somehow, but the run every run Ive done, they have both been great.

Ford Explorer ST 3.0 2023 tip 19.hpt
Ford Explorer ST 3.0 2023 tip 19.hpl

Thanks for the help! (Im also at 5000 feet so air pressure is only 12-12.2 psi or roughly 82 kpa)
