If buying a chip was one of the first things that I bought and it was programmed with my MAF and thats it,but now i wanted to add a differetial, throttle body and maybe some other things. I was wondering if i keep doing engine mods do I have to get the chip reprogrammed or do I have to buy a new one, or can I just leave it alone?
