Coyote X,
Thanks for the detailed info...perhaps I can steal more of your insight...
Max speed that I drive is 65. Here in my part of Idaho, Reg gas is 85 octane due to the higher elevation. Is 65 too fast for the 5-10 degree cam timing that you are suggesting? The engine is running pretty good after cleaning out the EGR and replacing the plugged PCV valve, but is has a pretty rough idle after it is warmed up. Perhaps that is indication enough that I need to advance my ignition timing?
