So, if you were already in the 400 whp range with a DCI, what kind of loss would you estimate with a stock airbox and same everything else? I understand that gains won't really be seen that much on a stock tune and boost levels, though I can imagine the gains getting rather substantial with higher boost.

I've driven some cars with DCIs and really didn't like the whooshing sound. It sounds kind of unrefined. I'm sure other people love it, just not my cup of tea.
