Boost Pulsating?

Hello everyone!

N54 with inlets, BMS intakes, charge pipe, stock DVs, and JB4. Daily driving at partial to medium throttle the boost is Pulsating, if that's the correct term. Basically high, low, high, low, high, low. And it's very noticeable when daily driving. When WOT there are no issues! On the Jb4 menu 10 is set to 3000, 11 to 1000, and 12 to 2800.

Has anyone had any similar experiences? Or any knowledge on the topic?

Currently no codes on the car.
