Fuel Pump selection

[Tech9Talon]

I just go my evo III installed. Now it's time to move on to the fuel mods. I was thinking about ordering the fuel management kit from Extremepsi, but I already have a walbro 255. I want to add 680cc injectors and an AFCII. I have heard that I will need an aftermarket Fuel pressure regulator if I run my 255lph walbro. Is that true, and if so should I got with a 190lph pump?

I ran my stock 1g fpr for a long time with my 255 with no problems that I noticed. I say the 190 would be fine for your goals but if you want the 255 go for it.
