Just did a log of block 211. Is this a good sign of a bad MAF sensor?
Been getting some lower then suggested MAF readings so i thought logging block 211 might help. It looks like 1st MAF# is what the sensor is reading and 2nd MAF# is actual air coming in. Looks like a bad sensor to me. I tried to clean the sensor but did not help. This is a hitachi sensor i just installed maybe 3 months ago with AWE stg3 kit. I usually cant get higher then a 240g/s reading out of it.

Doing some searching AWE stg3 should get more like 280g/s
My low MAF numbers give me a lean condition. I am running a wideband so i can see what the car is doing. I have to add primary fuel right now to deal with the low MAF values until i figure this out.
