FI fuel upgrade options

So why does he need a return system? For 500-700 HP, it is kinda silly to unnecessarily heat your fuel. Why not setup a boost reference for the FPR and then diagnose whether or not larger pump and/or injectors are necessary. I feel the injectors are small, personally, but it isn't my build.

That is a good question! I suppose that bit it just something that I have read over and over on here and taken as gospel. Perhaps not? Are there folks running boost referenced FPR's without return system?

Cosmo's advice is best, talk to CJM! Then report back here what he says so that future users can find the information in this thread =)
