Ya I noticed the same. When the engine is cold, the DPF % seems to start adding up really fast, like 1% every few minutes, and once it hits operating temps, it slows down but dam, every time you start it, by the time it warms up the DPF went up almost 3-5% which is unheard of. Wonder what it'll be like in the winter.Holy regen! Since i have had the gde tune i am surprised how often i am going through regen cycles. I have had one a week so far, about 100 miles apart. How often are these supposed to happen? I just had the egr recall done too, would that impact the regen frequency?
