I am looking at upgraded my 2000 F250. Currently, I am getting Diesel Power mag and I see all the trucks that have been uber modded and I am starting to get the bug. Running the 7.3L, I like the engine and I'm getting decent fuel mileage; average 16mpg. I currently have an AEM dryflow intake, 5" exhaust, and a computer tuner as far as power mods go. I have lots of other mods too, but that is probably noticable. At max power, I think I am pumping out 350hp and 700 ft/lbs tq. In the future I am looking at upgrading the turbo since the tuner is creating some surge, intercooler and tubing, high-performance trans, injectors, fuel pump, head studs, etc. My final goal is about 800hp and 1500 ft/lbs tq. Does any one else have a high performance diesel and where are you at?
