All going to depend on what type of FPR you get and if you need to up the fuel pressure to give you more injector duty.
If its a rising rate FPR then you will need to adjust the mapping likewise if your upping fuel pressure which is why i assume your going to fit one to give a bit more injector  duty.

if just adding the fpr and it is 1:1 as most are then just adding it wont be a prob but best to set it tp approx 2.8-3 bar with vac feed off and plugged and with it attatched shd be about 2.2bar or just under..if u dont have a wideband then just get it checked on r/road to be sure no lean area

If he\'s just adding a 1:1 FPR and running at stock pressures then there doesn\'t seem a lot of point doing away with the stock one unless its just for Bling.
Tell us what your plans are and what your fitting Mr JT
