modify my mustang has a deal going for xpipe mid pipe, sct tuner with cam tune, and jlt cai. will this really kill my gas mileage, also ofcourse you have to run 93 octane at the pump and that can get expensive these days, whats the difference between 93 octane and regular unleaded as far as consuption wise??. My stang is an everyday driver so is it worth dealing with a loud car and expensive gas prices????

Your gas mileage will most likely go down because its going to be a lot more fun to put your foot into it. The cam tunes run a lot richer at lower rpm also.
