everything said about these injectors makes sense, but does anyone have an explanation as to exactly what these injectors do for performance?

scientifically speaking. not just assumptions

the only thing i have heard is better throttle response, its the same flow flow rate so you wouldnt really get any horse power.

I've said this multiple times in this thread and I'll say it again.

A 4 hole injector will more efficiently vaporize fuel than a single hole injector.

Fuel that has been vaporized better will burn quicker and more completely, which will gain a very slight but still noticeable improvement in throttle response, power and gas mileage.

The only way to scientifically prove this would be detailed gas milage charts in consistent weather conditions, on the same route over a period of time using the different injectors and multiple Dyno runs under similar conditions.
