I've got a jdm B16a with STR fuel rail, adjustable FPR, short ram intake, aebs intake manifold, test pipe with magnaflow catback. Where should my fuel pressure be with these mods? I'm running a Phearable chipped ecu with a pretty stock base map. At low rpm's I get a slight ping. My distributor is right in the middle. Running 40psi fuel right now. Do I need to raise the fuel pressure to eliminate the pinging? Any info appreciated.

 

There really is no point in you having that fuel rail or the FPR.

But it should be around 38-42psi since its basically just bolt ons

 

rail and fpr were on the motor when i purchased it.
