My AFGs read 7-8gps at idle and only 209-213gps at WOT.

To my understanding at WOT the MAF should read 240gps, at 5800 rpms on a stock motor.

My question is can i recalibrate it to read correctly or should i buy a after market MAF to fix this, or are these numbers normal??

 

Long story short, don't buy an aftermarket maf. You'd just be opening a whole new can of worms.

 

I talked to bryan at pcm for less and he said that if my MAF is reading low and my MAP KPA is not going to 100 at WOT then i should replace the MAP sensor. He said this should fix the MAF and help out with the performance of the car.
