    Bigger injectors

    Hi new at tuning here had my tuner for a few years now and haven't used it question is how can I play with the fuel management in an 04 silverado that is completely stock other than they put 42# injectors in it and they don't want to put a charger on it

    Not quite sure what your asking..
    Do you mean how do you adjust the fueling?
    42# injectors are installed and what is "put a charger on it"?
    Do you mean a supercharger?
