if ecuteking or simtek no need boost controller best let ecu be in charge of this.
With above mods/spec cause of fmic wouldn't be bad idea for considering a uprated fpr. only recommend genuine fuelab/sx/aeromotive.
no need oil cooler..

easy. its an by pass of original. and then branch in with aftermarket reg on return fuel line.. set pressure. use only the 3 brands above.... don't consider others.
Woulda thought with your car about 1.35-1.4 bar woulda been average and normal on remap.

Your VF34 turbo has potential to around 360 bhp and your pink injectors on your OE FPR can support the injectors beyond 370 bhp.
The case for an FPR is when you want to extend the range of the injectors beyond what they can do at present and you will not max these out on your existing original Subaru FPR on pink injectors with a VF34.
