Hey guys please be easy as I haven't been on the forum for a while, and now that spring is near, im back. But hasn't anyone upgraded the fuel pressure regulator to a boost compensating style to increase fuel pressure during boost, or just plain increase fuel pressure by 5psi to help lower the AFR.. or is the fuel pump still the bottle neck?
I thought I read a thread that began with that concept but cant find it anymore.
I hate not knowing what my AFR is, and I haven't driven the car much since Ive done my mods. Ill be putting in a wideband this spring.
