This has been a great truck, I have owned it for 24 years. I have not chipped it or changed it from factory other than bigger exhaust, added gauges and airbags in the back. I don't drive it anymore and I am possible moving to Colorado and would rather not take it with me. I drive about 200 miles a day for work so that is why I don't drive it much, it is a lot of truck for my needs. I have never had any problems with it. I have changed the spring in the main valve body and rigorously changed the oil before 3,000 miles. The turbo is still in great working order and will spin the tires in second gear, too much power for my needs!
