    Default Looking for a stock LS7 data log at cursing 45-60 km/h

    Looking for a stock LS7 data log at cursing 45-60 km/h,
    maf, map, grams/cyl, rpm, timing, throttle % etc
    I am having issues with part throttle surging, pulling timing out/and back, just what to compare what the stock values are for map values.
    I tried just about everything, matching coast down timing, idle timing, base timing, turning off dfco, flat lining time, running sd,
    In open loop it doesnt seem to do it, The next thing I was gonna try is increasing throttle follower

    Is this in a stock app or swapped, stock tune or modified? If the timing is flat and its still doing it log TQ management and see whats cutting it.

    its in a 08 z06 so stock app, tune has been modified to run a cam 227/243 .649/.660 115 lsa,
    I have recently installed a ESC novi 1500 supercharger and 90lb/hr injectors, although this surging issue has been there ever since the cam upgrade.
    will do, I was hoping that you could log that with bbx, but the pid from some reason doesn't show up in the list,

    A stock rig and engine does not surge unless something in the modified tune makes it surge. I'd put money on tuning.
