MAF flow effects

[moss6]

Great input that, thanks! Don't know what TPS is though, help.

Another question; what effect do you think that the MAF's orientation to the the direction of flow has on its readings. That is that Banks recommended that the MAF sensor be rotated 90 degrees from its original orientation to the flow in the intake tract. Could that be something that would offset the drastic change in the amount of flow with the new location in the intake tract?
Also does it seem possible that the relocation could make the EGR stay closed?
And one more does a lean mixture in a diesel create more heat as it does sometimes in a gas engine?
