HotshotsHello all! I have a 2022 1500 ecodiesel. Question about tuning. Does that void the manufacturer warranty, or extended warranty, from the dealership? I was able to get the hpfp recall completed at the dealership a couple months ago. I went in for an oil change and they happened to have parts, so I guess I got lucky. Does anyone use fuel additives, if so, which ones?
