*I am not here to argue. This May or may not be an issue, I am not an expert mechanic. I just wanted to post my own results.
Car=2011 2SS/RS- HP MOD's=CAI intake, Apex scoop/washer bottle relocate kit, full Dynatech exhaust, no cats, JRE tune.
My MAF just shows a "J", picture provided. Data log snapshot shows what's going on. I've data logged a lot and also just watched the data on the gauges page and my "weak MAF" almost never dips below (*edit 1800mhz) 2000mhz.
Maybe there are just bad ones out there, kind of like everything else, I can't tell anyone that with certainty. If you have a "weak MAF", or even a "strong MAF", and have the ability to see it in action on a screen, do it. What can it hurt?
My .02!
