I have a 2005 super duty pickup with the 6.0. and while hauling some stuff it developed a problem and would note run ( Dead in the water ) I had to have the truck towed. I called K&J Diesel Performance and spoke with Jay Dearth, the owner and told Jay what had happen. Jay took the time to come to the house and check it out. He found one of the problems, but it just wouldn't start, so I had it towed to Jay's location on Cottoville Rd. To make a long story short, Jay found the problem, fixed the problem ( and in a timely manner ) and was very reasonable in price. I have my truck and couldn't be more pleased, truck runs GREAT. K&J Diesel Performance is a Top Notch Business and Jay Dearth ( Owner ) did everything he said he would, very pleasant to talk to and a man of his word. I would recommend K&J Diesel Performance to anyone. They are a 5 start in my book,
Thanks Jay
