You won't need to remove your maf, imo. As long as you keep it below 600rwhp (6spd) you can get by with (only) a fuel pressure regulator upgrade. It's critical that you keep it below this point, even including boost spikes and boost creep (i.e. don't set it for 600rwhp max/average, with peaks up to 625rwhp, for example). Of course, be sure to run a sufficient octane of fuel for the boost level you run it at.
With the aftermarket (adjustable) fpr in place, set base fuel pressure to about 55psi or 60psi, and then reduce fueling 0-3500rpms accordingly (using an AFC, emanage, or map ecu)...and then dyno-tune with care.
