Sup guys. I helped my buddy install a greddy turbo kit, the problems start here. The kit we got, was the emanage ultimate kit, but for some reason, didnt have the harness in it. also, the instructions it came with were for the origional emanage kit. So after I installed everything and finally got a harness from greddy, start it up, smokes like a mother. its white smoke and smells like it running SUPER rich, so rich it burns your eyes. Idle is pretty rough but doesnt stall out. CEL is on but i cant run the scan tool on it because it gives me a connection error im guessing due to the emanage ultimate. the e-man doesnt show any codes. Any ideas? ive been seaching the forums for the past 5 hrs straight and have found only bad news, and things i really dont want to get into. the car drives and pulls like it should. only problem being the smoke and rough idle. any help would be greatly appreciated.

Car has custom 3in midpipe if that has anything to do with it.
