"On this day it was clear that the K&N CAI was causing a lean condition, and that that condition would worsen when adding the CAT Back Exhausts. This is representative of the many enthusiasts out there who are or have done exactly this same set up modification. That is why there have been so many reports of Mach’s loosing the bottom end when modding with a CAT back. This is the condition that the dyno reported and is confirmed on this dyno and on this day that the lean condition indeed causes the loss of power on the bottom end. It should be noted that all systems tested posted both RWHP and RWT gains above the baseline dyno."

So I have this setup, should I put the stock air box and intake back on to get my low end back or get a different CAI .....anyone have any suggestions as to which I should get..... I wish I would have just left my f****** car alone........
