I put the title in quotations because Im sure this same kind of thread gets posted at least ten times a day. Anyway I am new to tuning, in fact I had a 2000 Si I left bone stock(i know a real shame) til i sold it a few months ago for my 2008 fg2. I recently have been reading all about tuning and being new to it all I am still nowhere near tuner savvy. I bought Cobb AP and it should be coming on thursday and one reason it was so appealing to me was because of the set maps. The problem is I am running a K&N typhoon CAI and Greddy Evo2 cat-back exhaust. I also have the stock header for the moment. So do I stick with the stage 1 or what are my options? Also I hear everyone say to use the software to custom tune but I was reading on the cobb site that its in beta testing and hasnt been released. whats the deal with that?
