If I am reading that right, your WGDC looks inverted compared to mine(0% = trying to close the WG, 100% is open.) You can see you are dropping close to 0% at the higher RPM where as mine would be the reverse and heading towards 100%.Thanks. Mostly what I took as the relationship. My wategate % seldom exceeds 70% or less than 4%.

Graph is a WOT run 0 to 90 mph on the Highlander AO, Green WG% red boost PSI, gauges show the line at peak boost.
Same log sesion with the graph reduced to the actual 0-90 run

It actually does seem to be doing the same thing that mine does. I am curious what your TIP Actual vs TIP Desired is.
My guess is its fine the way it is if you are ok spinning the turbos near the limits, but i am guessing your WG might be blowing open at high RPM which is why its flat lining near 0%. Your throttle plate is probably wide open and your PCM is demanding a higher TIP Desired than you are getting for TIP Actual so its doing everything it can to get the number higher.
I think Ford might have tuned the wastegates on these to blow open as a fail safe. Mine pretty perfectly blows open at 220,000 rpm which is the safe compressor speed limit for the 2013-2016 turbo.
