Ok, I have a problem. I bought a steeda CAI and I read that it requires a tune. I cant afford the SCT tuner, and some other people have told me that I dont need to get it tuned, all I have to do is pump some 93 octane and the car will run fine. I'm having a hard time trying to figure out what I can do because I dont want to mess up my car, but I really dont want to wait any longer to put in the CAI, can anyone help?
