2008 vrs bmn enginge code

back story car has been remapped and had the dpf deleted. (not by me)

about 3 months after the remap, at 3k revs its developed a noticeable flat spot the about 3400 rpm it picks up again and starts boosting.

no fault codes

on live data on the snap on verus nomial boost requesting 2500m/bar, actual boost 2604m/bar at 2982 rpm

am i right to believe the car is over boosting and the ecu is backing the boost of as a safety precuation and that this is being casued by sticky vnts in the turbo ??

Yes that could be happening, or it is just overboost without sticky vanes. it is a common cause for these engines to overboost, especially after its been tuned. i would say you could try by adjusting the N75 first and see if that helps, you adjust it based on your boost loggings
