High RPM Tuning Advice ?

Out drive is repaired, she made it back on the water for the weekend. However the T4 gasket didn't arrive, figured no need to map the turbo drive pressure with it still leaking. Opted to drink beer and party with friends on the river.
Did manage to clean the MAF but it didn't restore the airflow values back to where they were tracking last year. Only changes to the intake system have been the addition of the velocity stack to the 4" intake tube. According to some other posts out there, when you ditch the stock LLY turbo intake tube and air filter box, you should change table B0201 values to stock LBZ values. So while floating around today, I updated the values in the tune.
Not sure it's any closer to being calibrated better now than it was before, but it sure impacted the low end fueling. Back to rolling some major coal when it spools. No matter what your DSP calibrations are, the stock MAF tables defiantly come into play. The exhaust smoke verified that..
Now I believe the MAF is reading higher than actual flow, what you guys think"

from those maf readings it would put you around the 600hp range, which is normal for the turbo to produce
