Loosing boost at 3k rpm X5 35D

[Citizen]

Hi there,


Something strange with my car (no both the EGR's, no PDF, no AdBlue, remap)

With the full trottle on the 3th gear it's loosing boost at 3k rpm from 2 bar of gauge pressure to 1.4 bar and coming up slowly to 1900 mbar (1.9bar) only at 3600 rpm.

As I can see from a TIS programme something must changes at 3k
What's wrong, need help.
P.S. New hoses and valves (half a year), new both turbines (15 months), so may be not very new.
