Is there any benefit from fitting a FSE fuel regulator to a STI 5?

Does anyone know the stock STI regulator pressure rating and what is a good setting for the FSE.

Is it recommended? Also, is a special adapter requrired for install?

Thanks

Hi there,

One simple question... what are you trying to achieve by fitting this reg ?

People tend to fit adjustable regs to force more fuel through the injectors...especially if there are max'ing out.

Just fitting an uprated reg, without doing anything else (especially an FSE one) will cause the engine to run rich in certain places.

I was on the impression that the FSE can improve my trottle response.

My car is on stock boost of 1.1.
