I have read through the site and am trying to understand injectors, I mean I know what they do and all but if I were to upgrade to a bigger pound injector and have my ecu sent out to be tuned accordingly would I have more power? Does more fuel equal more power? And with a mild cam would it be a good idea to step up from 19# to 22# maybe even 24#?
Thankyou.

 

Yes it's a good idea. When changing to a bigger cam valve timing holds out longer to get more air in and exhaust out faster. More air and more fuel is more horse power.

 

You match injector flow to how much hp you are trying to make.

Injectors give zero hp. They ONLY make it accessible.
You will gain no power from bigger injectors UNLESS they are too small and LIMITING power.

 

One of the most important pieces of info you need when sizing injectors is horsepower.
Bigger is not always better unless you have the appropriate mods to accommodate for the increase in fuel.
