  • bigger injector size question

    ok heres the situation, ive got a 93 grand am with a 3.3L (3300) v-6 , and the injectors are royaly screwed, i used an 1/8th of a tank of gas idling for 30 min today, ok, so i need new injectors and i have some from my 91 gtp 5 speed that i think are good but they are probably bigger, so my question is , will they work, 23lbs/h in my 3.3l? i dunno im guessing that there is 19, 20 lbs/h in it now. i knnow they should fit but am i going to over fuel the engine, or will i need to have the comp tuned or something. the only mod i have done to the car is i heavily ported the intake and TB. thanks
