what are the benefits of an aftermarket fuel pressure regulator????

 

You can turn up the fuel pressure to get more fuel.. only downside is that you lose MPG.

 

To my knowledge that's not completely true mike. With higher pressure the fuel atomizes better, and any chemist knows with more surface area, you get better reactions on any chemical.

With WOT that may be true, but regular driving wouldn't be the case, and if you're lean you may get even better milage. Considering that you will burn up more fuel.

....unless i'm completely wrong.

 

You may be right.. all that I know is my fuel mileage seemed to go down when I had the AFPR put on. Maybe it's because I was flooring it more often
