BOX SENTRA

well i put my transmission back in the car, and now i barely get any boost i think i might have 5psi by 5000rpms, its horrible. i took of the o2 housing to look at the turbo blades and they are fine, no excessive shaft play, and the turbo spins very freely as always. took off the wastegate, cant find anything wrong with that. all bolts are tight on the exhaust manifold. did a boost leak test, no leaks, holds pressure fine. is there anything else that could cause boost issues like this? like if the car is running rich or something?

Timing.

i did a boost leak test, no major boost leaks....my a/f ratio drops down to 11.0/10.9 when i try to get on it......i dont think it should drop that low until its in boost... my car did throw a maf error code and was running really bad a few days ago, i cleaned the maf and it hasnt thrown another code, but i think it might have something to do with my problems.
