Will Bigger Injectors Kill Gas Mileage??
OK, I swapped over to 60lb injectors on my 8.1L for the turbo. The turbo isn't currently on, so Im just running a tune similar to stock just modded for the injectors. Seems my mileage had dropped (if possible on a 8.1L) since the install. Used to get about 12-13, now I get no better than 9, and its been like this for over a year. I know the injectors just allow more power, but actually add NONE. I'm not sure what the problem is. Seems there is something a little wrong somewhere, maybe a Vacuum leak on an injector? It never wants to idle smooth

I agree... the injection systems on our trucks are controlled by computer and will supply only as much fuel as is required. upgrading to bigger injectors will not affect mileage unless otherwise tuned.
