is this a weak maf causing my bad gas mileage?

I checked my maf and here are the results.

.5 at ignition on which is normal 1.3 at idle which is low but normal (1.3-1.7) AND 2.5 volts at 4k rpm which fsm states approximately 4 volts. Could this 2.5 volts at 4k rpm be the cause of the bad gas mileage? My car runs pretty good and no particular issues of bogging or surges or bad idle. Checked timing and did all my tune-ups. i'm on edge as to what it could be ruining my gas mileage.

BTW. I had a ram-air setup and after the install.. poof.. there goes my mileage so that's a big clue.

did you check these voltages at the MAF or at the ECU? That makes a bit of a difference IMO... what the ECU sees is more important that what the MAF reads.....
