    Ok so yet another surging hemi thread.

    I was hoping to not have to resort to this but I am looking for assistance with the mentioned issue in the title.
    I can idle relatively fine without any surging in P/N. Even drive for that mater, however its on the shift from P/N into drive or reverse I get a few swings in rpm then more less settles down. Fueling appears to be ok... VE tables could be cleaned up a bit but I don't think they are terrible. I am assuming my issues are in the PID idle control but could also be the min air flow or throttle body table. Ive got through and read just about every thread on idle control ect.but I more less ran out of patients today. attached is current tune and a short log Appreciate any input or suggestions I should look at.
