Guys, put the vehicle in Cruise Control and head down the highway. As you approach a very moderate hill you will notice the boost gauge go from vacuum to boost without a change in gears and little, if any, change in rpm.
Did I say I love the sound of a turbo spooling up?
I had a 5k stall on my Buick. Talk about a crazy sound.
(Just thought I 'd throw that in for fun.)
