how much extra gas is used when switching from 19 lb to 24lb injectors ??? say if i was making 20 mpg now what would it be approximately after the switch ??

There are more variables to this. This question cannot be answered properly with what you've given us. If you're just switching from 19s to 24s for the fun of it, don't.

actually i posted the question on the top end kit thread ...so for instance if i went with the trick flow kit and 24 lb injectors , would that help ?

also in regards to that previous thread ...........as far as research ... are you guys saying trick flow is the only company whos parts work well with its own parts such as h/c/i ??? like the holley intake is better than trick flow but its heads are not as good ... so youd have to buy a holley intake and research what heads work well with them ???

You're not gonig to use any more gas with 24# injectors than you would with 19# injectors as long as it's tuned or calibrated properly. If you get bigger injectors, the computer will compensate by simply reducing the pulsewidth. You car will need a set amount of fuel to reach the desired A/F ratio. The amount of fuel isn't going to change based solely on your injector size.

As an afterthought to add more info... Larger injectors aren't going to give you more HP either. You get larger injectors when, due to your current mods, the ones you currently have cannot supply enough fuel to reach teh desired A/F ratio (their duty cycle gets into the high 80s or higher.) At that point, you need bigger injectors. Of course, you will get less gas mileage too, but it has nothing to do with your injector size. Needing larger injectors is a result of other power-adding mods. Just as an increase in HP or a decrease in gas mileage are also results of power-adding mods.
