thanks guys...can someone explain to me whether the installation of one of these is plug and play or is tapping of the secondary injector fuel rail necesary???

 

Can someone explain what is wrong with using the stock one?

 

If you're running a large race port then you would need larger injectors and upgraded rails to get the power out of that engine

 

Aftermarket regulators are adjustable so you can tune your car to its maximum potential. The stock one is not.

Plus if you upgrade your fuel lines to deliver more fuel putting the stock one on the larger lines would just add a constriction to the system. The goal of your fuel system is to deliver a consistant, sufficient amount of fuel to your injectors - so a free flowing system is better than a constricted one.

Oh and how many of the stock things stay useful when you start to upgrade these engines?
