Hello

Ive read on here somwhere someone is running 21psi by wiring his coldstart valve to a boost sensor that kicks in at x psi.

How much fuel does the cold start valve drop in could i get away with doing the above mod and running 18psi on std botttem end with just big intercooler?

I was thinking of doing the above mod and taking it to scc and get them to set it up.

Also what is the fuell pressure mod and will i need it for 18psi?

thanks Paul.

I run mfi rs turbo lump in an xr2
