Headers change AFR?
Headers change AFR? Is it possable that with the LT's installed the stock 02 sensors are reading a little off?
My PLX is not matching up exactly to the ltft's. When my WB02 err is just about 0, the STFT's are about -3 to -7, and the LTFT's are -5 to -9.
I know that my wot was falling in specks (890-900) with my stock manifolds. When I put LT's on, the lowest I could get it was 930.
What should I tune by, fuel trims or wb data?

WB data. just make your fuel trims 0 to about -4, you don't want positive fuel trims, as if you hit a cell going on your way to WOT, and it has a positive fuel trim, it will carry that fuel into WOT and other effects
If I understand this correct the car ecu will not make its fuel additions or subtractions according to the WB. It goes by the data that the fuel trims provide, this being I probably need to ahve those correct. My STFT's are very close to my WB. My LTFT's are off in lala land (way negitive like -8 or -12. )
Think it will be ok to disable LTFT's and tune from stft and wb only? will the ecu still do what is should with the ltft disabled?
