which mods hurt gas mileage?

[acidangel316]

thanks for the info.. i'm sorry, i just got back from work and wasn't thinking too much. i only wrote down my engine mods. i do have both the pro 5.0 and 3.73 (how ironic you mention those exactly) and as far as exhaust goes i have full-length bbk's with the stock cats now. i am working on ripping them off and putting some flowmasters in their place. when i'm done with that i'm going to go to houston performance and have them dyno my car and burn me a chip. that's was my master plan. now i guess i'll have to add some heads in there. i didn't want to because it's a nice chunk of cash for some decent ones. any suggestions?? but as far as the fuel does go, does having bigger injector's hurt my gas mileage(i think so cause it uses more fuel but i'm not positive) and if so relatively how much??

-thanks, josh
