hey guys I've been out of the loop on dmax performance for a while now and am looking to get back into it some. I am currently in the process of trading a lbz for a lmm and want to delete the dpf and get better milage with it. I see the question has been raised whether or not efilive will allow a delete of the dpf or not. Could someone clear this up as to whether this is true or not?? Also with the proper tuning what could a guy expect for milage out of a lmm?
