Is there any reason why you shouldn't run a 20vt without a MAF connected?

I've been told that it doesn't matter too much as there is another
flow sensor that is used anyway?

Also was told though that some things get shut down, like the TCS, when this isn't connected. I know the TCS light comes on but is anything actually disabled because of this and will it do any harm to the engine?

Not so much another airflow sensor, as it drops into derived tables for throttle vs rpm vs barometric pressure..... to calc its settings.

Read on Vortex of peeps doing it.

I would'nt personally.

You will in theory also see less MPG if you disconnect the MAF as it will result in a richer (safer) mix, which means wasted fuel

Mine was faulty and when I looked at it basically it was open circuit so the same as having it unplugged... Eventually it turned on the check engine (pollution light):(
