I hope when you say fuel pressure you actually mean via a GOOD ECU tune and NOT via AFPR (adjustable fuel pressure regulator). go with bigger injector that what you THINK you need b/c you will most likely want more power out of it after you play with what you have. it is easier to down play your injectors that it is to go beyond what the flow rate is (saves you from having to buy bigger injectors later down the road!)
