Black Dawg you are correct about all the same plungers. The turbo pumps supposedly do have a different timing and fueling curve than earlier pumps though. Certainly somebody with the know how like Mel's guy or Ken could bring any 7.3 pump up to turbo specs but I kind of doubt without adjusting those curves a stock 7.3 pump is anything but that. Having said that a well built stock 7.3 pump can make a ton of fuel and you'll probably find other limits before you "run out of fuel". I don't know why so many people here are anti-reman. You should know that they are a mixed bag though, what some builders call "reman is shameful, nothing but cleaned up...these are no better than your old ones and maybe worse. Some are reground, and some truly have new nozzles (by far the minority). The moral is test, don't guess, even with new injectors. You want them to be 2000 psi+-200 psi and the lowest one within 50-100 psi of the highest for best economy and power. When you match a set the idle is so much smoother too, let me tell you.
