Got a B16a with prelude injectors (270s...?) and a katman modified p28 ECU/. When you get on the throttle, LOTS of smoke comes out of the thermal exhaust. Hey, cool running rich is safe but I'm guessing I can pull back a bit. I'll be getting a B&M fuel pressure regulator and a gauge (as well as a VAFC) from JDMspec (who have great prices, BTW). What sort of fuel pressure should I be shooting for? I used to have a boosted car and static and idle fuel pressure were important factors. Is this still the case with a NA car? I know that injectors do not affect fuel pressure but I'm wondering if there is a good range to be in.

thanks!
