On the air tube lower connection. Is there any space between the bottom of the tube and what it connects to that would let the air tube go lower?

I'll look at it again tomorrow, but I don't think so.
Look at the 1st picture I posted and see how short the rubber hose is.
My suggestion would be to buy another metal tube, remove a section of the necked down area and TIG weld it back together.
Then you could chrome it.

What does that device do? A gulp valve?

Volkswagen Mass Air Flow

I was getting error codes and check engine light in my 1.8T a few months ago. My VAG tool came back with "mix to lean" errors. Max boost I could build was 5-6 pounds. Apparently fairly common on 1.8T engines, the mass air flow sensor had gotten dirty. The fix was to remove (no special tools needed on VW) and soak the sensor in 70% isopropyl for 5 minutes. Now back to 20 pound peaks and 10 pound sustained boost. No CEL errors either.

Cleaning the MAF sensor wires is common in the Ford Mustang community. I do it every 5k miles on our Exploder and will use it on our SVT if it ever gets 5K miles on it. You're supposed to disconnect the battery prior to cleaning, so the 'puter re-learns the mixture.

I pulled my MAF on the 2.8 Coupe and cleaned the sensor wires, waiting to see if the butt-meter detects anything.
I used a can of CRC Contact Cleaner (electrical) I got @ Lowe's for $6.98 and followed up with a blast of air from PC Duster® can. (Supposed to be the best cleaning agent vs. Gumout or Q-tips w/alcohol per Ford forums)
