    2009 GT500 throttle issues

    Hi guys,

    I was hoping to get help with the throttle issues I am experiencing. 50% of the time, the throttle is closing, and staying closed during the 1-2 shift. The car runs great otherwise, and any help is appreciated.

    I have attached the file, and here is the vehicle info:
    2009 GT500
    KB 3.2
    KB 168mm TB
    1000CC FIC injectors
    KB boost a pump
    E85 fuel
    Kooks Headers and exhaust


    Thanks in advance!

    Do you have a wrench light come up on the dash when it does this?

    I would say that it might be the max boost pressure under the supercharger tab but you say it happens between shifts.....no lift? or you coming off the throttle between shifts? May have something to do with your torque tables also....im no expert just some thoughts.
