our family purchased 5 brand new 2012 LML's (father inlaw bought 2, myself, my parents, brother inlaw,) all from the same dealer. Loved the trucks! Having owned previous duramax's we were quite impressed until our Canadian winter set in. 4 out of the 5 trucks had serious def issues, freezing tanks, clogged dpfs due to idling thus needing a manual burn off. two of these trucks were used in my father inlaws heavy construction business, so yes they idled a lot during the winter. father inlaws business is in remote northern Canada, so they trucks had to be picked up and put on a flat deck and taken out 4 times EACH!!!! and for a business man that's huge dollars lost. So after the 4th time he had reached his limit and was phoning for quotes from dodge and ford on a 2 brand new diesel trucks and told our dealer he could pick up the pieces of shit from the ford dealer. THEN like a miracle angel out of the sky we find out about H&S performance...... let just say about a week after finding out, every LML we owned was fully deleted with 4" MBRP duals. WHAT A DIFFERENCE!!!!! it now runs as a diesel truck should and like our previous duramax's did, RELIABLIY and after heavy discussion with our dealer in regards to our issues and our loyalty to him and the fact that we've spent over a million at his dealership he is honouring our warrenty to the fullest degree. Having said that we drive like grandpas, were not in it for the extra HP at ALL we couldn't care less if the tuner SUBTRACTED some power if it meant getting rid of the god awful def/dpf system. We all couldn't be happier with our trucks now. Ill tell ya, after having my young family stranded twice in my dually because of a def issue at -50 on the side of a remote highway, the decision was more than easy to delete all that crap. Needless to say I think GM needs to thank H&S for keeping customers. I know my father inlaw may be the "small guy" compared to some but he was prepared to switch over his whole work fleet to dodge (20 trucks)..... I know with the way the EPA is going its tough for GM also.... but at the same time when you spend 70,000$ on a truck it sure is a kick to the nuts when it dosent perform.
