My Stalling Issue

Ok guys so after I installed my supercharger, I've been having this issue with the car stalling out as some of you may know. It stalls out when I shift out of gear into neutral while the car is moving. I therefore have to keep it in gear when coming to a stop or shift into neutral and rev the engine to keep it from stalling out. I have cleaned the throttle body, replaced my intake, clean my maf sensor, tried a new maf sensor, and attempted to get a retune. I am still throwing code P0102 which says low circuit on the MAF. Trifecta tuning says it is a MAF issue while others say its a tuning issue. I am going to do some datalogs once I get my tuner cable to see if there is absolutely anything that he can do. Otherwise I am stuck on ideas and almost tempted to just go back to being NA. What else can I do guys?

Holly Shizer, you're supercharged now?

Nice, but from the sounds of it it's still sounds like the TUNE that's not getting along with the MAF sensor. Either way can you get your hands on a new or used but verified functional MAF just for testing purposes?

Blazerlow is of no help and hopes you get this figured out.

Moral support is my best offer.

ok if replacing the MAF didn't work, that prolly means the tune ain't working. Are you feeling any roughness in any other circumstances?

That is interesting. My buddy was having the same issue with his 350z. Sounds like a maf sensor issue but then again it could be alot of things. It may be the tune. Vince should be able to go thru a datalog and figure it out though. Anyway my buddy had this problem after he put his body kit on and took his z to the dealer and they recalibrated his PCM. They said the bodykit was causing airflow issues.

How did you guys rewire the MAF?

Unplug the MAF and see if it works any differently.
