That makes sense. I was told by one diesel tech here that the stock fuel rail would have to be replaced because it is a one time use. This isn't the guy that is doing my head gaskets but a different guy. Is that a BS statement? So if the truck is already tuned you would just leave it alone and not mess with the fuel system at all? What about doing the EGR delete? I know my truck was not tuned for that. If I can find the original tune guy I do remember him telling me he would redo if I altered those things. IF I were to NOT reprogram but have done an EGR delete what can I expect?
Again, sorry if these questions seem incredibly stupid. I have not done any reading or homework on any of this stuff in over 2 years.
Woah!
One time use on the fuel rail? That's complete BS!
You might need to do something later on with the FRPRV (Fuel Rail Pressure Relief Valve) but not right now, you'll know you need a new one or a shim kit if you throw a P0087 code (? I think that's the code?)
Yes, aside for the addition of a good dual filter lift pump leave the fuel system alone. It's fine for what you're doing. My personal preferance and suggestion would be to get EFI-Live tuning and ditch the bully dog or whatever flash tune you've got right now...
As far as the a EGR goes, the blocker plate is the quick answer. It's cheap, fast and gets the job done, and if you need to smog your rig it can be easily removed for the test and replaced after. For guys that have to smog test I always tell them to have their tuner leave the emissions controls active for the optimized stock tune on their DSP switch, that way when they go to test they have the ability to have full EGR functions and no CEL lights on the dash.
With EFI-L you'll have quite a bit more power on tap, so you're trans will be your limiting factor. I wouldn't mess around with a shift kit on a 5sp Alli, you gotta tear it down about half way or so to do the install, so you're better off just doing the whole build, especially at the mileage you're at now...
That's bs on the fuel rail. And I recomend doing something with the egr. You could install an egr blocker plate for around $20 and save some cash. But you'll still need the egr disabled and codes blocked in your tune.
