Hey hey hey. My first VW was/is a turbo diesel. I installed a vac/boost gauge and then wondered why it didn't have any vacuum like all my gassers. Got to start somewhere. He may not be very bright, but ya got to figure this kid is probably 17/18 years old and never took auto shop. Then again, you really should know if you have a turbo or not. I can't give him any out for that. He's probably very well versed in installing neon lights and aluminum tail fins.
