Loosing boost on 2013 Z4 35i (N54)

Hi guys.

Has anyone ever experienced boost loss at around 3k rpm upwards?
My gauge reads a max of 9/10psi on hard acceleration (stock engine) up to 3000rpm then goes down to 4/5psi if I stretch to 6000rpm.

I ve ordered Forge upgraded diverter valves as I think the problem lies within the factory ones.

Any feedback will be highly appreciated

Thanks!
