I am running a stock header with no exhaust Question how much will it lean out the motor.I put in a power programer map to get me started runs great up to 9000 then dies until the rpm drops. The air fuel ratio meter shows i am running barely on the rich side then at 9000 it goes super lean then shuts down. Am i on the right track to richen up the map? I unplugged the power commander and stock computer is doing the exact same thing only wont rpm past 6500.

If you truly want to make it work properly you need to get a custom map made for it.
