Hey all, I have a '15 LML Silverado. Few days ago got the Service Exhaust Fluid on DIC and the accompanied light on cluster. I have appointment to bring in to dealer but trying to decide whether to fix what's wrong or just go ahead and delete the thing. Been back and forth about deleting it, just bought it used this past year and don't want this to begin a landslide of DPF problems. Would rather just invest in tune and straight. My concern is just driving home for the weekend it went into the reduced power mode, 65mph max. Not sure if dealer will clear that and if I put a tuner on it will I be able to clear it? Any thoughts, input, ideas, past experiences would help greatly.
