    Is this running normal? LM7 5.3 03 RCSB

    Was looking at my logs for my truck

    03 Silverado RCSB previously a v6

    05 Tahoe LM7 5.3/60e combo swapped in
    Running Vette regulator
    Volant CAI
    Other than that basically stock

    Sent in my ECU in for basic tuning for the swap for VATS and other sensor
    Tuner said he does mild base tune for stock

    Got everything in and running normally from it seems
    looking at the logs and I want to say timing looks a bit high on WOT
    Just want to make its running safe as is

    The timing in that tune appears to be final fully tuned timing. You might want to put a stock 5.3 map in it at least until you get the fueling and bugs worked out. Your pretty lean for the most part due to MAF being relocated or skewed or whatever going on... Fueling needs to be fixed before you'll want to run the full timing. You might also want to put your maximum knock retard settings back to stock too.
