well the stocker keeps throwing a p0103 so i need a new maf but im not sure if i should get a stocker from advance auto or autozone or napa or get a 85mm and get the 3 pin to 5 pin harness adapter. i would also need to get the maf retuned. i have a slp lid and a shanner s3 throttle body, and a stock bellows, if i get the 85mm i will need a new bellows right? and also a bellows for the maf to hook on to the lid.
what should i do?
wondering if this maf problem is cauing me some mph at the track

 

The outside diameter, IIRC is the same size, someone correct me if I am having early onset oldhammers disease, lol. Anyway, I have a brand new Z06 MAF that I just had on my car one time for testing purposes. I would give you a deal on it as I got one myself, being a new unit. Another, IIRC, the Z06 MAF goes higher in the freq range and it's really not hard to retune to the Z06specs, I have the MAF retuning spread sheet if ya need it. It's a no brainer to use, just plugging in some numbers and changing your look up tables, and/or doing some logging for flow data. One day i Will be adding this as a write up to my site, as we need to retune the intact tract every time we make a change. let me know. Actually, for those reading along, I have two Z06 units, with one being a polished job. I have now gone to the 90mm unit, so... Oh I just thought, you have the cable throttle and I have fly by wire, so forget what I just said, lol.
