Well here's the deal. My 99 F250 is starting to nickel and dime me with oil leaks and fuel leaks, I must have done 10 O rings in the last 3 months and now I'm either loosing my High pressure oil pump or something attached to it. One thing I cant stand is a truck that marks its territory. So its about time to do something about it. I'm trying to decide if pulling this motor and rebuilding or swapping a CR in it is the way I should go. I've been poking around here looking at what is available for the motor and it seems to me that there is no where the information in this forum as there is in the 7.3 ones. Now for the questions, I want to know what I need for upgrades on the motor. What is a available for chips? From the little I've seen everyone talks about a "smarty" but this seems to be a programmer, is there anything any good that is a swap on the fly type system? My end goal is a good DD that can handle towing my big trailer and be faster than all my friends Dmaxs running intake/edge/exhaust.
