Default Problems with the new boost control function

before the update the Boost Duty cycle used to be at 100% until it reached its target. But with the new function with basic mode/setup mode/advanced in closed loop i have some problems
The boost duty is always 0%. When i go WOT it jumps to 100% for a second and almost immediatly it jumps something around my 60% target. Even at 105kPa it isnt 100%


Lower limit kPa is set to 170kPa.. Is the algorithm different in the new firmware because the old closed loop worked good and spooled very quick because it stayed at 100% until it reached my target



Any help please? Not much info on the new functions yet. I included my tune and small datalog
