    Default no timing change

    I have an 05 ls 5.3 w/Atomic EFI and 6010 timing controller.
    no difference in any of the six pills or with custom timing curve setting it from 0-50 degrees.
    having a bad run on with temp readings from 150 degrees up.
    had this problem even with the 600CFM Holley I ran for a while. been doing this for 3-4 years. I replaced the 6010 controller once during this time.
    car seems to run good but the run on is killing me. engine runs normal temps between 179-186 degrees...180 T-stat...2 speed fan w/shroud (Atomic controlled)...aluminum 2 row radiator.
    cold starts great (down into the 20s). no hot start problems.

    When you say "run on" I'm assuming you are referring to dieseling.
    Have you checked the spark plugs? Have you tried running a colder plug?
