So I just got into the Evo game with a Cosmic Blue '14 GSR *woot woot* and Im looking at picking up the AEM CAI with some more mods in the near future. It will be an on and off DD and I'd eventually like to get to ~400hp. I've read through some threads about the Cobb set up and I'm convinced on getting it but, do I absolutely need it the moment I install the CAI? I've also been told by a friend that if I do decide to go Cobb that I'll have to get it tuned elsewhere since they won't (not sure how valid that statement is since he drives an STcry). Just need some insight or someone with the Cobb AP that can give direction. Thanks!
