I made that name back when i was in the market for a truck but could not find a 7.3 i liked that had under 100k on it so i bought my 04 and love it...although i have had some issue's not due to injectors that i know of...but like i said to everyone his own im just very picky about my oil and keeping it clean...thats why my by-pass was one of the first mods...if others have good luck with it awesome...i just wanted to share the fact that ford states against it...but they also state against fuel additives....good luck to all those running it.
