could it be the actuator?

ok well i have done a boost leak test and took car of that, i just got a fmic installed, it seems like first gear doesn't get full boost to almost 5.5k on a big 16g, 2nd gear takes about 4000, 2nd and 3rd feels nice and strong but first sucks, could it be the actuator is sticking open a bit? if so how would i check it, and on the piping for the fmic, hot side is 2 1/4 cold is 2 1/5.

How big is the fmic and how is the piping run? Mine reaches full boost by 2800-3000 rpm with fmic with 2.5 ic pipes with coustom route. Im kinda in between stort route and stock route. I also have the b16g. Need more info to give a more precise guess.
