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...

Once in 20 years, but really because I just felt like it. All my experience with MAF sensors is they lie just downstream of the air box and before the throttle body. So the only real reason they can get dirty is with an extremely dirty air filter or oiled gauze (K&N type) air filter. Other than those reasons they should never get dirty or need cleaning.
MAF sensor is not the same as a MAP sensor. Both are generally found on turbocharged vehicles and only one(usually a MAF) is found on N/A vehicles.
The MAP sensor on a diesel is usually right around where the EGR valve injects exhaust gas back into the intake so they tend to get clogged a lot more on a diesel.
