I'll eventually try this...but won't like the noise when it's punched....the throttle that is.

It's true on my Cruze too. The airbox opens right to the engine bay without all the fresh air crap in the way. I can also hear the turbo spool with the excessive intake stuff removed, so it's an auditory reminder to get out of boost when possible.
