I traded my 2006 5.9 on a 08 6.7, hoping for better luck. My 5.9 started droping injectors around 60k, the dealers computer didnt pull up the overinjecting injectors. I had a fuel knock for about 20k then pulled a heavy load, melted #2,#5 pistons. Dealer replaced motor but I was afraid to pull with a fuel knock. I also have a stock 94 5.9 362k. What are my injector options for my 6.7? Thanks for the info you guys are great!
