Hey guys,
just got my x3 calibrator. I noticed that when you go to upload the custom tunes from bama u have the options to change several features like fuel to air ratio, gear shifting, and much more. My question is, are the tunes from bama their optimum best? or is there a guide out ther where i could learn more about what each option does.. im scared to mess with it without reading something because i dont want to screw up my car..
