Sorry for the slight derail, but does anyone have any suggestions on mileage and nozzles? Meaning my 08 F350 has 163k miles, and the 09 im buying my wife has 80k, woild someone suggest I have my sticks rebuilt before putting nozzles on but just install the nozzles on my wifes? The billie guys say once you hit XXXk miles you need to have your injectors rebuilt before installing nozzles. Just wondering if its the same on the 6.4 platform. Again, sorry for the derail but hopefully it answers questions for others that might be interested like myself.
