We have a 99 Dodge 350 diesel. We bought a BD chip and had it installed. Worked great went on a 15,000 mile cross country trip. It seemed like I never got out of 6th. gear. Mileage got better more power etc. A year later took the truck to Cumins for some work (non warranty) removed the chip before taking the truck in. They upgraded the program in the computer fixed my problem and when I got home reinstalled the chip. We left for Alaska and started having fuel problems. Acted like it was out of fuel. Changed filters several times no help. Got home took it to Dodge store (warranty work) asked them to check fuel pump. It was bad. They replaced it (warranty). Back went the chip. Out went the pump. Twice. Now I have a$600. chip on the shelf. The reprogramming brought my truck up to "chip performance" and adding the chip doubled it. Burning out the transfer pump. So be careful about chips.
