Thanks all for the helpful suggestions.

I modified the  KFLDIMX 800, 1000 table data by  the same 20% that I had adjusted LDRXN; while capping it at a max of 95 I saw elsewhere in the stock table.   Ive  read KFLDIMX does not scale linear but figured this would be a good first attempt.

Updated XDF that has this map is attached along with the updated bin and log.

Improvements are seen in the log and actual boost tracks well with requested boost up to about 3500 rpm. Duty cycle after 4500 rpm is 95%.   Not sure if futher adjusment of KFLDIMX will help as I interpret this to mean the turbo can no longer provide requested boost at higher rpm based upon physical limitation.  Please let me know if this is wrong and further KFLDIMX adjustments are needed.

Unless someone suggests otherwise, I will taper my LDRXN so the actual boost can match requested boost.  Perhaps I should be looking at a turbo efficiency map?
