I have been reading over alot of forums about the 200k mile tune up. So far what I have gathered is to do a tune up I should replace the IP, Injectors, Glow Plugs, return lines, get the timing done, and flush the coolant system.
I'm looking at going through R&D, I am a little confused on the N/A injectors vs turbo injectors.
My plan is to also add a 3in down pipe into a 4in exhaust, then add a pyrometer and add more fuel too it.
Is there anything else I should look into or do maintaince on for the truck?
