Well seeing how your argument completely disagrees with everyone else in this thread I would say you're wrong. Bio, blue and Matt have all said my intake is not a restriction at my point in modding. So you are saying they are all wrong as well?
I have a canned tune that was ordered while I had the HAI and I told Will to tune it for the HAI, so if anything I would be even faster with a better tune for my CAI.
I do not have a wideband, wideband tune or tuner so I do not know my AFR, I only know how much timing im running because my buddy tuned out my KR and gave me a MAF tune. He just got the tuner not too long before he did this for me.
Overall I know a decent bit of ppl running WizAired intake on their fairly decent modded cars. One of which has an XPZ, stage 4 ZZP heads, 3.0 Gen 3 with OD balancer (so basically a 2.8), 20* timing with no KR setup and he says he will never switch to a HAI. I would be willing to live with his setup, he seems to be doing "okay" with his WizAired intake.
