I think you may have misunderstood what "B" meant when he said Off Load. Maybe should have been worded more like under load. The turbo will spool up sooner under load than "under loaded" Hence when you tow with a turbo you generally see full boost and full TQ much much sooner than regular driving. generally 1800-2000 under load than 2800-3000 no load. This will be seen when used with a big truck like the H2. I personally would like to see a turbocharged H2 tooling around town blowing the doors of sport trucks might make for a nice change.

It sounds like you are saying that an engine loaded up at a given RPM will create more boost than one smoothly running at the same RPM. I don't know if I agree or disagree with that completely, but if I had to say right now, I would disagree.
The engine only moves so much air at a given RPM. Just because reverse pressure is being applied through the driveline and the vehicle is working harder to pull a load at that given RPM, it wouldn't be moving more air through the engine. Turbos are as much a product of engine RPM as screw superchargers. If the RPMs are low and the turbo is not tuned for that low of an RPM, creating more load through the driveline would not increase the exhaust outflow thereby increasing the boost from the Turbo.
That's my opinion and again that's the first time I have heard that theory so I haven't had time to give it much thought.
