In general most aftermarket intakes will throw off the fueling if the maf scaling in the tune is not adjusted.
the grimspeed intake and the misimoto intake seem to be the closet to stock maf scaling and are generally ok on stock maf scaling.
The stock tune runs quite rich at upper rpm heavy load so the black smoke is likely fueling, and might be worse due effects of aftermarket intake if not tuned.
as you said maybe a pcv has failed and your letting oil into intake that way hopefully thats the white smoke
as the other guy said check your coolant level, hopefully it not using coolant.
check you have no exhaust leaks near or before the 02 sensors as this can cause fueliung issues
assume oil is not overfilled ?
if it all looks ok, put it back to stock and let the dealer look at it if its under warantee
