I have a 2002 7.3 w 80k miles. ive done the Donaldson/ford air box, 4inch turbo back no muffler, transmission just got complete service and added a bullydog shift enhancer, autometer gauge pod with trans pyro and boost. dp tuner with 80hp econ and towing tunes, what would be the best most sensible order of the following upgrades and what specifics would you recommend.

1. injectors
2. turbo or at least impeller
3. hpop
4. fuel system upgrade
anything else??

im not looking for ridiculous power or anything that will end up degrading the life of the motor im just looking for rock solid long lasting reliability??

 

get rid of the DP and your about as reliable as you can get. the rest depends on what you do with it and what kind of HP you want.

 

tp38 wheel for surging help.

trans mods if you want more power.
