    U0107 loss comms with TAC module after swapping out locked ecu

    Hello,
    Attached is a log of the situation and current tune loaded.

    Customer brought me a 06 silverado with a 5.3 head/cam combo to tune. Ecu was locked so we got another and put it in. Licensed, turned off vats, flashed, started truck to put on dyno and threw code. Figured nothing of it strapped down cleared code did some basic calibration changes to make truck driveable and idle. First attempt at a pull throws code. Clear code and test again. Can handle quick stabs of throttle but anything slower application of throttle it throws code.

    Customer says he drove truck before mods and after mods with no problems.

    Something i'm doing or order up a part..... throttle pedal or throttle body?????

    thanks!
