high sulfur is a tune that is offered by H&S that allows off road use, if you have a new mini maxx then the only way for you to get that set of off road tunes would be to send a form to the epa and then they make it so your truck cant be registered for highway use.
but anyways you can still run ultra low sulfer (15ppm) and i dont think you can find high sulfer commonly. i think off road fuel is 300ppm?
