Not if you get the correct injectors.... and sorry no I don't know myself !
For 350 bhp you should be o.k. without an FPR, I have one but that's to stretch to 400 bhp !

P.S. get some new seals, and "lube" them when fitting, to avoid leaks....

No need, as stated above raising the fuel pressure just allows you to get a bit more fuel into the engine. Mine has had the fuel pressure tweaked by 0.5 bar as an alterntive to larger injectors to (hopefully !) make it into the 400's.

P.S. a dyno run will identify any fuelling problems, AET at Castleford have an offer on till the New Year.
