No mate a standard FPR is well upto the job.
As long as it's set to 3 Bar with the Vacuum pipe on and 3.5 bar with the vacuum pipe off it will be ok.
A standard frp will have a raising rate of 1:1 so for every 1psi of boost you run the frp will raise the fuel by 1psi.
Which is exactly what you want.
