Just to keep the terminology straight:

Turbochargers, superchargers and blowers all compress air coming into the intake with a turbine.

Turbochargers use the pressure of the exhaust gases to drive the turbine.
Superchargers use an electric motor to drive the turbine.
Blowers use a belt or chain from the main crankshaft pulley (like the A/C compressor, alternator, etc.) to drive the turbine.

Ouch !!

I concur. That's nuts.

I would take the truck to a couple independent mechanics, and get a diagnosis. Have them fix what's not under warranty, and then take it back to the stealership, with the documentation from the other mechanics, and raise hell with them until they do the warrantied work.
