Its a highly disputed topic and it is hard to document any gains. Even with consistent dyno runs, the gains from a charge pipe alone would be hard to realize on paper.

However, if coupled with a performance dropin filter such as AFE/BMC/MS/etc and some scoops from AFE/RPI/MS/etc....the gains are very real indeed...
