Any gains (power or mpg) by combining the Hemifever tune with CAI?

I'm pulling the trigger on a Hemifever tune. Would like to get a CAI for a little more sound & pep from the Hemi but not interested in spending several hundred if it really doesn't add any performance.

Anyone combined these two already or gotten feedback from Hemifever on gains heard directly from the tuner on whether there's anything to be gained?

Thanks

I can't find anything on this website or even on the web or Hemifever's website claiming added gains by combining the tuning with an intake so I guess it's not much of anything. Oh well. $250 saved I guess. Surprising though considering other cars I owned (all GM LS engines) had big gains by combining intakes with tunes

Seems the WK2 and V8 intake flows pretty well OEM. The sound is better with a CAI, however. I think just about everyone here already had a CAI on before the tuner... so its kinda hard to compare. I was going to suggest perusing some of the SRt forums, or other Chrysler product, but I think you will find the same thing.
