Ess 625 boost issue?

So I have the ESS 625 kit (6spd manual) and I'm only hitting full boost in lower gears 1-3rd from a stop. However when I am on the highway at approx 75mph in 4th gear and floor it, it barely sees 3psi all the way to 8k RPM. Here is what I have done so far:

-New Maxrace BPV
-Brand new belt I think it's the 6110, 5mm smaller than what another member recommended in another thread. It was difficult getting it on.
-Brand new tensioner
-boost leak test done and holds 10psi with no leaks whatsoever

It just feels slow on the highway and fast from a dig which is strange to me. Any thoughts?

I know nothing but I would imagine that to be some sort of bypass valve.

Strange problem.

Maybe a bad check valve at the fuel tank breather underneath the manifold?

I was thinking this as well.

I am getting a shadow code 27CE that keeps coming back even after clearing. Not very much information on here except possibly EKP module? Low fuel pressure?
