4.0 BAR FUEL PRESSURE REGULATOR

[markgti1.8t]

hi there was on ebay looking for a 4 bar fuel regulator and on some adds people keep saying it will add more bhp is this rite or will the car need mapped be 4 you see any differences

[Wazzzer]

nope won't add bhp but can add more scope for fuelling. Some tuners such as Revo won't map to stage 2 without one. PM me if you want one

I added one to my stage 2 custom mapped K04 car. As above, Revo state it as a necessity. Injectors were right on the limit on the 3 bar, although 4 bar does add a bit of extra strain on the fuel pump iirc.

I ran 3 bar on my ko4 agu, niki said it was fine.

Depends on tune revo say 4bar with stage2 and APR when fit k04-001. I've GIAC tuned ecu for mine not fitted yet stage 2 that reqs 4bar with that, not used it yet tho.
