My truck had lost power and wasn't running well. Had taken it elsewhere with no improvement. Thought I may be looking at getting a new truck. Had several references for Dan at Diesel Works. Just got my truck back and it runs like new again. Everyone at Diesel works took the time to listen to my description of what I had been experiencing, then did thorough diagnostics to pinpoint and fix the problem. They were very professional, patient and kind. Would highly recommend their service and integrity!
