Kevin,
Did you get a check engine light as well? Your '02 truck has the VP-4400 fuel pump and a low injector volume could cause this perceived turbo problem. If the VP-4400 starts acting up it sometimes throws a code with the associated CEL. In this scenario you'll also have a drop in power and/or hard to start.
To explain further, your turbo extracts heat energy from the exhaust and converts this energy into boost. If injection volume is low exhaust volume will be low and you won't hear your turbo spool up in the normal way.
Gauges, EGT and boost, would make this problem easy to diagnose.
Sorry I haven't given you any answers, but you might be barking up the wrong tree.
