What other mods do you have ? also what BEF are you running?
I can see there is over boosting on map 6 then drops, but on map 4 holding the boost with FF 148. Have you pressure test the system to check for boost leak ?

I'd say you still have a leak of some sort. Have you checked your intake inlet to make sure it's fully on the turbo?
