1999 passat gls 1.8t(aeb/k03)

so for some reason my car isnt boosting, peak at like 1-2 in 1st and 2nd and no higher then 3-4psi beyond that.

smoking a bit but not like a blown turbo(prolly due to catless and 1 o2 sensor being run)

It doesnt sound like a blown turbo or act like it, but im curious what the problem is? dv? N75?
