i just installd JWT s4 cams on my s13 red top broke them in and checked my plugs and there really white.....i have no afc or rom tune just bolt ons, any way to make it run more rich.....does any one have a similer set up.I took maf readings at wot it was like 5.20 is that past the stock maf range and could that be why its leaning out.i was running 12 psi and set it back to stock for saftey reasons will be checking plugs again.Would a rom tune and z32 maf fix this problem. as of now dont want afc or a bigger turbo right now.

If you want to run a little more rich, turn that fuel pressure regulator up a bit and check your plugs again.
