Engine/Transmission (1998.5 - 2002) boost ?

It should be easier to reach max boost while towing versus running empty due to the extra heat, right?

You have the right idea. You need more fuel to make more heat to make more boost which makes higher exhaust temps which leads to bigger turbo and bigger exhaust and it keeps snowballing :-laf .
