Could someone please explain how to test your MAF to see if you are pegging out or not, I know its a volt meter thing, but I don't know what to look for, or what wires to play with on the maf itself, and do you do the test in netrual and just rev it to see how high the volts go? or do you run temp wires in the car and do a run up the road or what???? I would like to see how close I am to pegging out and whats going on with it to see if I need to bother with upgrading just yet.... TIA!!! :beer:
