Bosch 4-bar fuel pressure regulator...a wise choice?

[M_souren]

The cars basically stage one. Im looking for a smoother power band and a friend has a 4bar laying around. Will it even make a difference if i throw it in?

You know the stock fuel pressure regulator you have in your car already is a bosch 4bar fuel pressure regulator right? So you'd pretty much be putting the same one in.

Don't change the FPR unless your tune calls for it. Also ^.

You should already be running a 4-bar. It's the stock FPR on the A4's. No need to change it.

wont do anything, plus you arnt making enough power to actually need to mess with the fuel pressure
