rough idle when i hit 2500 to around 2700 or more
 

alright so i just got my ecu tuned from e-mance and now my car feels like it has a rough idle when i drive it or just gassing it from around 2500rpm.
but then after that my rpm will go up smooth.
i just installed a n62 z32 maf on the ka24det and before i got the ecu tuned it was working fine.
i not sure what it could be
i did some searching and it could be a dirty maf or bad wireing but then i know for sure that i did the correct wireing and for sure that the maf is CLEAN! and working fine.
anyone might know whats up?
i was planning on takeing the car to e-mance and getting my ecu retune.
