Fuel pressure regulator

Im trying to increase my fuel pressure in order to get more power. Now, may manual says that if you remove the vaccum hose from the fuel pressure regulator, the fuel pressure will rise. Should i do that to increase my fuel pressure or are there some unforseen negative effects im not seeing?

ok you will increase pressure but if your injectors can only flow so much, how are you gonna push more fuel through. i would say get bigger injectors at the same time at least.

shepherd79 is right. BIGGER injectors first if you want to increase the fuel flow into the motor.
