I'm looking at upping the power soon on my 98 v4 sti, mods so far will be walbro 255, full decat, green panel filter.and then I will finish it off with a esl remap. Would you recommend anything else like a fuel pressure reg? Im hoping for 320-330 bhp. Do You think I will need one? Thanks

probably not needed at that level bud. i fitted one on my wagon and it was mapped by andy f and he didnt touch it! lol still running standard fuel pressure now at 315 bhp. it gives the mapper options when mapping but upping the fuel pressure puts pressure on the rest of the fuel system and unless new rails and lines etc were also fitted its probably best left alone. some more knowledgeable guys will be along hopefully with advice.

You won't need an FPR. An Induction kit then FMIC would probably be the next mod.
