Any good obd2 chips to increase mpg/ delete dpf? 3.0 blutec
I just realized all my problems have happened after an updated part for emissions was added. The part was changed because of water damage not by dealer. But after the emission part was changed mpg went from 35mgg hwy to 23hwy and 28 city to 17mpg city. So if I can unplug something or plug in a mpg tune that would be great. Sorry for spelling.
