I recently purchased a 2000 5. 9 4x4 and am loving it. My truck only has 130k and is in great shape. I just installed a Magnaflow 4" exhaust kit from front to back, ordered a cold air intake and have an Edge superchip. Also it's had an upgrade on the automatic trans. Future plans are FSS fuel pump, maybe some after market injectors and intake. First I need to study up on diesel engines more. Also I'll be adding some 35's to the factory wheels later this summer.
