Fuel Pressure?

I just bought a 98 Ls that has the b18c5 motor/tranny swap.It has high compression pistons,v-tech controller,walbro fuel pump,straight exhaust with no cat,and when you get on the car real hard it puts off a fuel smell in the cab and the gas mileage isnt hitting on much.A few of my buddies have told me the car is obviously running way to rich and are telling me to buy a fuel pressure regulator.If I buy 1 and install it on the motor how will I find out what fuel pressure I need for this motor.If anyone knows what I should do please let me know.Thanks
