I still say that Bosch has been making high pressure injection systems for awhile and I am sure they know how to make them. IMHO it is still dirt related. We were saying that only 01's had the problem well guys its all the way to the 03's now. I think real world results and George Morrison have a lot better handle on the problem than the boys at GM. With the help of George and everyone putting on extra filtration I serious doubt you will see injector failure in those trucks again or at least it will not be in the near future.
