Fuel pressure needs to be increased according to boost, you can't just set it at 70 PSI and be happy, since when you are only at 2 or 3 PSI (or at idle even) you're car will run pig rich. You need to use an FMU.

Also, fuel pressure is decided based on the expected hp output and the injector size that you have.

Then you need injectors, and with bigger injectors you'll need an adjustable FPR.
