cai install question

just installed cai and getting poor idle smelly exhaust and a little smoke from exhaust.

the pictures are what i have been running for a while now w/ no problems.Its a pro m 77 mm maf calibrated for 24# injectors.I have 19# injectors but it runs fine.I am pretty sure there is no chip in the computer.when i installed the cai i was forced to use the stock maf housing but still used the same maf i've been using.Is the problem using the maf for 24# and the housing for 19#?any help appreciated

I had to use the stock housing because the current one has four bolt holes and the filter bolts to it.nowhere to clamp the tube on.I dont need 24# injectors yet w/ my setup so i guess i have to get an aftermarket maf housing for 19's?
