Tuning issue or not?

Ok so I got a '12 6.7 tuned by Tyrant. Basics done, exhaust, cai, def and egr ****** with cold and hot side upgrades. It has ran great since It was tuned couple yrs ago. In that time the egr cooler was still on it and just unplugged. Made 30 psi of boost and it came in pretty quick. So yesterday I removed the cooler and put the plates on it. Now, boost is slow and hits 22 then under full throttle when it shifts to 4th or 5th it hits about 29psi. No codes or anything. Does this sound like it's in the tuning?

check the block off plate on the manifold for drive pressure leak. Pretty hard to blame the tuning when that was something you didnt touch lol
