Turning off the injectors would cause the engine to stop running..... Injectors also have a MINIMUM flow rate. If that rate is greater than what is required for correct mixture at low RPM, you WILL run rich. No tuner in the world can fix that. That is why we have injectors with various flow rates. If it was a 'one size works for all', there would be no reason to HAVE different rates.

Dont have to believe the NEW GUY but this guy seems to know his stuff.
How does the boosted guys run 60's ? There not all ways into the boost at idle,cruise ect. 2bar map 1/2-1/3 of the resolution changes them 60's to 30's or 24's.

Thats why they call it custom tuning. 1 size can fit all if you like. ALL WAYS best to run a larger injector and cut it back.

So yes you can go big but it's not always recommended

The boosted guys also run adjustable fuel pressure regulators. (which is another way to 'fine tune' your injectors.) Using a vacuum (pressure) signal to alter fuel pressure will change the effective flow rate of the injector. Of course, these guys spend some serious dollars to have the ability to do so.
On the doge trucks, the fuel pressure is NOT vacuum modulated, you get line pressure ALL the time. So using that particular method is not workable, without serious alterations to how the fuel system works.
Quite simply, if an injector pumps out more gas at minimum pulse width, than the engine needs, you will run rich. End of story. If you run a fixed pressure system, such as found in the dodge trucks, there is NO way to correct that.

in some cases though, boost, for instance..... being able to expand the 'useful range' of your injectors is sometimes easier than other methods. (extra injectors, or, whathaveyou.)
