MAP sensor filter and vacuum hose replacement

[motorbreath]

I have been suspicious of my MAP sensor readings since I had my 5th gen e-tuned last year. The readings fluctuate constantly, even while maintaining a steady engine RPM and throttle input. Before I spend the $$$ on a new MAP sensor, I am going through all of the hoses and searching for a boost leak. The obvious first thing to do was to replace the MAP sensor filter and associated vacuum hoses...which seems to have had a noticeable affect on the stability of the MAP readings!

This might just be my imagination, but a super cheap thing to do, especially since I am not using the OEM shaped vacuum hoses (see the zip tie!).

I just came across this and it seems like an amazing idea for our decade old cars. Have you tried cleaning the MAP sensor too?

I assumed that the original filter kept it clean and was getting clogged, didn't want to risk cleaning the sensor.

It seems to be working fine now, so I think I'll leave it alone since I have a laundry list of other stuff to fix!
