Either you have a bad MAF or you are at high altitude.

Bosch MAF reads low when failing...so I'd say bad MAF.

Bad MAF is my guess as the "big blue" is only a couple miles away.

Default Take a look at Block 032 and post the results.
You can also log Block 211 on a WOT run and see how actual and expected MAF values compare.
