Looking to do some weight reduction Soon and been looking at tuners first. I don't think I would have to buy a $1k plus Spartan tuner because I don't see what the difference in tunes could be compared to the rest out there. I originally wanted a H&S but since theyre out of business i won't be able to get updates. So I was wondering what everyone else is running for their dpf/def delete and what made you go with that brand? I heard from someone that there's a brand out there that sends free updates every month or so but they could not remember the brand.
