Just wondering if it is normal to hear my turbo spooling up when climbing hills on the highway, I believe it is normal when laying into the pedal, but just putting regular driving loads on the engine when highway driving, I'm not so sure about. Thanks,

ps-I have an 05, 3500 with the 5.9

 

Any time you add more load to the engine, whether its pulling a load or going up a hill, you are going to hear the turbo more if you are trying to maintain speed.

 

brian is right birch, the turbo is just doing its job. its a beautifull sound!

 

What about when your slowing down and the exhaust brake kicks in?

 

exhaust brakes are going to make a lot of noise when they are in use, they basically just plug the exhaust pipe causing a lot of pressure to build, but yes it too is normal
