Do i need a fuel pressure regulator?

[sanitarium16]

Im going to get my car dyno tuned and i was wondering if i put in an adjustable FPR would i see bigger gains? I put in PI H/C/I and i am in need of a tune badly. What are the advantages of an adjustable fuel pressure regulator?

98 mustang gt, 4r70w automatic (pi swapped)
JLT Ram air cai
Pro-M 85MM Maf
FRPP 70mm Throttle body
BBK Intake plenum
Steeda UDPs
MSD Ignition coils/FRPP 9mm Wires
Mac off road h pipe
Flowmaster super 40 catback

i would suggest getting one.. you can always adjust the fuel pressure for more fuel or less considering you have a better flowing fuel pump rather then the stock one and their not expensive... Kirban is a good regulator alot of people in my city use them and their known not to leak... its also good to have if you have bigger future plans for your stang
