What AFR?
As the title says, what should the AFR be at idle and at full boost?
i have a my97 wrx with decat down pipe n back box, hks rs induction kit, hks headers, blitz boost controller set at 1bar.
i believe if it's below 12 your running rich, 14.7 is normal at idle , i'm not sure what it should be on boost though? Also when is the car running lean, what if the AFR rises on boost? to what level can it rise and still be safe? (if rising is safe in the first place)
