Boost code with no leak

Hey everyone

I have a bmw 335is e93 with upgraded CTS turbos and I’m facing a weird issue. Sometimes when I am driving I notice my MHD monitoring app shows my target boost for example would be 8 and I’m only pushing 4 pounds of boost.

I will then get a code for low boost pressure, I clear it and it still only pushes half boost. I then turn off my car and turn it back on and the issue goes away! Back to full boost. I really don’t understand what it could be, I’ve tried changing my boost solenoids and that didn’t fix the issue. I then tried using a smoke test through the inlets and I didn’t see any smoke come out from anywhere. I’m not sure what the issue could be. Any ideas?
