What are the syntoms of bad Z32 MAF?

[JDMSIL80]

Im trying to narrow down the problem associated with the cut-out issue of my car.

I bought my Z32 MAF from local junkyard, the car seem to idle and drives normally just like stock.

Only issue I have is now when I boost over 10psi, the cut-out would started to occur at 6000. The higher boost I go, the sooner it cuts off.

What are the chances of me buying a bad MAF? I assumed most of you guys are running used MAF just like I am.

Can you list out the syntoms and problems of bad MAF so I can see if I really need to buy a new one.

Thanks!

I had a bad maff and the car wouldnt rev past 2500rpm so that the symptom i had.

Im unable to boost any higher than 11psi with GT28R or it will cut off around 4800rpm.

Would this be one of the syntoms and its time to get a new MAF?

If you check the FSM, it gives you the procedure for checking the MAFS.

I do not have the factory sevice manual, my 180SX is an imported vehicle from Japan.

Is there link I can refer to?
