K&N Series 63 CAI
Just did a before and after dyno run on our 07 LTZ. Run 7 is stock and run 9 is after the installation of the 63 series CAI. Also the series 63 is enclosed in its own airbox while the series 77 I believe is not that could also explain as to why the 63 series makes more rwhp.

Numbers are almost identical through normal operating range. Up around 5000+ yousee the seperation. What's up with the big hiccup around 3500 rpm?
I'm really starting to believe that the factory setup is optimized for real world.
Sorry to be skeptical but this kinda shows what everyone is saying... Increases are not where you need them, if at all.
Get 8hp at 5k plus and lose 10 to 20 whereI need it.

I think the dip in power in the begining could be an adaptation of the ecu. You can see how the AFR became alot richer at the top end than when it was stock. Gonna put some miles on her this weekend then come next week gonna re-dyno again before I install the JBA cat back.
