Ok
I don't think or know if any of them could be of help compared to the Tech 2 value we look at during acceleration to see if the air mass meter start to get lazy.
The Air Mass deviation value in % is a value calculated inside the Tech 2 based on what the T7 box is feeding it which is based on all sensors in the system.
It can go -25% and +25% but should be around 0% most of the time during stable acceleration or cruising.
But this value has to be learned to use since it can fluctuate a lot in weird ways depending on if you have air leaks and boost leaks after air mass meter but before turbo or after turbo but before throttle or after throttle body.
So the more weird problems you see and the more you use the Tech 2 and the more you learn how to use that value, that's when it becomes a great value/tool to use.
