Bonalume fuel pressure control

for:
Alfa Romeo 75 V6

Alfa Romeo 164 V6

If your engine runs "lean", so it only gets less petrol, and you increase the fuel pressure with this fuel pressure regulator, you will immediately achieve a noticeable increase in performance. If your engine is already running well, you will not feel any improvement with this fuel pressure regulator. If your engine is already running a bit rich and you install this fuel pressure regulator, you can even lose both power and torque.
