Low boost and rougher idle after engine pull

I pulled my motor this past weekend and did a lot of work to it but of the things I did I think my problem may be in the manifolds I replaced or up-pipes, and I also did the wicked wheel and non ebv outlet and pedestal. When I accelerate it takes until 1850-2000 rpm to build any boost at all. The little rougher idle may be due to the cam sensor but I'm looking for any input on the low boost numbers and unresponsiveness and the rougher idle. Thank you and looking for any input!!!

auto or manual? What type of W.W. you installed? How many miles on motor since re-install. Theres air that needs to be purged out..100miles or so, to get back into its normal condition.

Auto, 138,000 miles and I've put 150 on since the job. I had trouble with the manifold to up-pipe connection there was a small gap but I got it to seat properly. Could be me just imagining it

i'd put a few more miles on her then check for soot. You could build a boost leak detector and have at it.
