I'm scared to drive my car because I have GENIII's and AAM 2.5 S-Line midpipe and muffler delete. But I have the software just not got a tune yet. So it's up to you if your strapped I saw wait unless you have other mods.

From what I've read and understand, the reason it goes lean is that CAI's will often throw off the MAF readings being fed to the ECU.
