    I am not 100% familiar with the throttle body you are using. Do you know how large the IAC passage is compared to the previous throttle body? There are some tables in there that define how much air...

    One thing to try is to adjust the throttle body so that the IAC is not open as much. What is your IAC reading with a warm engine at idle?

    Other option is that if you have the Tunerpro XDF file, you have enough information to make a CAX file to use in EFILive. Then you could make these changes inside EFILive.

    Rumor has it that this particular case was caused by their handheld (e.g. pre-programmed) diesel tuners. I don't believe that it was due to SCT's tuning software.

    B4308 Airflow Parked table

    This is probably a silly question, but I am wondering if the airflow parked table {B4308} is related to where the IAC starts at when you first start the engine. The description hints at this since...

    From my looking at LS1B OS's, my guess is that there is a setting in the System segment which controls it. There are quite a few different settings which are not mapped out in EFILive. If you had a...

    Yes, the gassers is what I was trying to clarify. I know this is a Duramax thread but the fact that the gassers are now also screwed will affect a much larger base. Very sad to hear.
