Air/Fuel ratio on turbo b16 6psi

I just bought a 00 civic si that is b00sted.. It has AEM managment and gauge and was told that my air/fuel ratio was high.. I was wondering what it should be at or around?? I am running 6psi if that matters.. I am new to the BOOSTED WORLD. Any info would be great on how to keep up with it.

Out of boost just cruising around 14- 14.7 is ideal..

when your under WOT and in boost 12.0-12.5 in the AFR

On a b16 with a c/r of 10.2:1 I would say more like 11.5:1-12.0:1 under full load in boost.

^^^ we got U. I wouldn't go anything above 12.0. id say 11.8-12.0 across under full boost would be fine.

Idealistically you should be running between a 12-13:1 AFR at WOT as that is the AFR where your best power will be made. Running a richer AFR cools down combustion VERY slightly and adds a bit more margin of error. Many individuals claim that you should run between 12-13:1 AFR and use your ignition timing to offset any sort of detonation or issues like that.

On a 10.2 CR.. Keep it a bit richer, it will help keep it cool.

Mid 11's at WOT.
