  1. #1

    Lightbulb Cracking issue ( CTS-V)

    CTS-V 09 can not be start normally without little gas pedal, mostly in normal temp but in cold stat is perfect, I tried to increase the startup airflow and tweak the cranking timing but no improvement.
    so how can I reach to perfect startup in warm temp

    Car mod
    • Whipple 2.9
    • H/C
    • ID850
    • 90 throttle



    looking for your replay ^^

    in your initial tune, your cranking table did you reduce it or keep it stock?

    try reducing from the original map around 40%
