Hey how are yas? I have a question, maybe someone can answer.

are all x4's technically the same? the reason i ask is i have an unmarried 7215 (for chrysler) sct site says i need the 7205, i understand that, but is it only the tunes that are different? if i get a tune emailed to me, will it load the ford tune onto the "for chrysler" tuner and load into the car? sorry, dont type that often, dont have the best grammer.
