Default slight bucking 4th gear pull

On a 4th gear pull ( it does not do it in 1st,2nd,or 3rd) starting at 4000 once it gets around 5300 there is a bucking sensation no flashing cel (utec) but yet it feels like timing being pulled. We changed the vacuum lines and boost controller. It holds boost fine 1.8 down to 1.6 at redline. Plugs are new and gap is 28. Changed maf and it reads 4.5. Where do I go from here? I have a version 7 long block sitting there. What about using the coils from that? Could they be the problem? I do get misfire codes, but not often. Thanks in advance Michael

Maybe you could get a bigger maf pipe to make the reading lower? What kinda gas are you using? What kinda engine/turbo? You're running a lot of boost huh? How much power does that thing put down?
