No, Fuel Pressure will go up, unless you really want to get it back down you'll need to get an adjustable one..

iF EVERYTHING IS STANDARD, including boost it will run very rich because you have now ultered the pressure which in tern alters the amount of fuel delivered unless the pressure does not increase exponensialy, depending on how much the FP increases you can compensate by increasing boost.

It should not flood the motor, if you plan to keep everything standard and it is over fueling alot, you need to bring the FP down to standard.
