    2.8 Duramax Timing

    Has anyone played with their SOI timing for cruising and mid range the 2.8 is retarded to -6.5 deg in this area.
    I know NOX and engine noise will increase if advanced but fuel economy should improve, I was thinking going to 0 deg.

    Not sure about the SOI timing but you should be able to play with the pilot pulses to counteract the increase in noise.
