    Does anyone have any experience with Ally claims, do they send an adjuster out to ensure no modifications have been done to the vehicle, and do they allow you to use a shop of your choosing for the repair work? Thanks

    Hi folks new here. Recently I drove a ford superduty that you could view the Dpf % from a menu on the dash display. Does the Chevy have this feature? We had issues with the ford where we were not in a position to “drive to clean the Dpf” and ended up taking it to a diesel shop to perform a...

    So I bought an 08 lmm 6 or so years ago and it had the dpf removed with only the cat remaining, I'm assuming for a muffler? I've just now gotten around to doing an egr delete as I scored a good deal on a ppe cold side pipe that is a 2 piece allowing the grid heater to be retained. My question...
