I was thinking of getting the SCT X3 tuner and was thinking if all of you think its a good tuner. As for the tunes, are the ones that come with it good? Also, where can I get custom tunes? Are they free? Also, do the street and towing tunes that I can get (or come stock with the tuner) kill mpg? Because I have heard the street and/or towing tunes create a lot of smoke and if the smoke is unburned fuel, wouldn't mpg go down (I should say I don't mind the smoke, in fact I like it :D)? Thanks
