Best to test it with a boost gauge as discussed below.

There is a moderate power increase felt that starts between 2500 - 3000 RPM, but not a neck-snapping explosion that you would feel in a modern hi-performance car. Sometimes I can hear the turbo whine on mine but not always. Depends on ambient conditions, and never when the radio is on.

Yes, good idea, and not hard to implement. Tee it into the small tubing running from the rear of the intake manifold to the boost diaphragm (the "flying saucer") on top of the injection pump. IIRC, D24T stock boost should be around 10 - 13 PSI, D24TIC may be higher.

You will want to get on the TB situation as addressed in your other post.

Sorry, IDK, not so familiar with the IC as unfortunately we didn't get the IC version here.
