Hey guys im a new member here this is my first post. I recently inherited the truck my dad bought new in 1999, a 2000 7.3 F250. He bought a new truck and told me to do what i wanted with this one. I currently drive a 2005 5.4 F250 so its cool to have a diesel toy. This truck just rolled 410,000 miles and the only thing done to it was cosmetic stuff a starter, oil pan replacement and ball joints. (other scheduled maintenance too). I am currently doing all the body work on the truck and converting it to the 07 look. I need some help with things i can do to improve performance, which injectors ( im sure it needs them after 400,000+ miles) chips, tuners, turbos intakes and whatever else i could do to make some more power without destroying the motor. On another note i can get a pretty good deal on a 6'' bds lift and mickey thompson atz 38.5". do you guys think this would be too much for this old girl. The truck still runs great not as much power as she used to have but im sure thats due to dirty injectors and turbo. Any input or things you think i need to know would be greatly appreciated. Thanks!!!
