MotorTrend published an article today. Sounds like they had the GM CAI we all have been waiting for. They seemed to like it. Not much meat to the article, but the interesting thing is that they call the GM CAI a concept. Must still be working on the tune as everyone else has stated. Just thought I would share as this is the first I have heard of anyone trying out the GM CAI.
