    LSX 454:

    11:1 Compression
    Bore is 4.185 x stroke 4.125
    Pistons are stock size
    Crank is GM p/n: 19170391
    Combustion chamber on heads : 70cc
    2.20 intake / 1.61 exhaust

    Cam is 0.635 intake / 0.635 exhaust
    236deg intake duration / 246deg exhaust duration

    The truck starts normal when cold, but when it warms up you have to give it throttle to get it to run, and then it will find idle and be fine. But any slight throttle when its warm and it will begin to surge, sometimes stalling.


    Hope that helps!! and send me a config file if there are sertain PID's u want to see on logs. Im still very new at this. Thanks alot!

    ETC Area Scalar needs to be raised to around 7300

    PE Enable TPS is too high.

    I'd zero out PE Delay RPM.

    Why is your Stoich value set at 14.97? and I hope you're not tuning this thing by adjusting your PE table.

    this is a file on your file
    you can compare what i have done
    if this one didnt workout
    shot me with your Stock file car

    by the way ,, you need bigger fuel injectors
    better fuel pump
    i dont think the silverado fuel pump will handle this power

    adjust your windeband so we can read
    good luck
