How often do you clean your MAP sensor?
I used to clean mine every oil change at 15k, but now I do it every other oil change since the EGR is not spewing soot all over it. I have seen a dirty MAP sensor have a significant impact on performa...

Many of our company trucks never threw codes when the sensor was clogged, but definitely showed signs of reduce power and increased fuel consumption.
From what I was told, a clogged map sensor is slow to respond to pressure changes or gives a false pressure reading than actual therefore telling the engine to give the wrong amount of fuel. It can do this for a long time before actually throwing a code since it is still telling the engine a pressure that is within its parameters, just the wrong pressure.
