I here that allot of people get a canned tunes with there CAI , and have a lot of success with them!
I went to a dyno shop because I couldn't get rid of my 02 errors to quit after I got my longtubes. I also bought the C&L Racer CAI that doesn't come with a tune.
Here is my Dyno with my CAI just sitting there loose. After the dyno they fastened it down.
