Great service and great job! Came to me and cleaned the DPF filter on my Freightliner. Whole service took less than 2 hours. Showed me the filter before the cleaning, weighed it and checked the back pressure. After the cleaning they weighed it and checked the back pressure again to show it was truly clean. No need to bake it and the whole service was a hell of a lot cheaper than the dealer quoted me just to "service it before it had to be sent out to bake for an additional charge". read more
