Yeah I've been able to see in my UTEC logs how it leans out my mixture. Much the same as how the atmo BOV richens up the mixture a little right after a shift. I guess somebody could use the two to even each other out, but since their effects are in different places in your powerband, I doubt it.
Oh, to answer the original question, if your engine is stock (stage 0 or 1), you should be rich enough that adding the CAI shouldn't make you lean enough to detonate.

Thanks for the info Pat
.What exactly did you log on the UTEC to see it lean out (injector duty cycle, mass flow) or did you have the wideband O2 hooked up? I gotta get together with you and Richard when I get my UTEC.

The WB (techedge v1.0) and the UTEC's built in knock correction.
Dude, the UTEC is awesome, but I ain't gonna lie to you. It took me probably 6 months before I was to the point where I was smart enough to tune it to go faster.
I can't speak for Richard, but I will always try to help out if I can. I will say that I'm not an absolute tuning wizard. It's just damn difficult trying to tune, 1)having to learn from scratch what you're doing, and 2)having no AWD dyno available.
