Should I ignore my 02's????

[jonnygsx]

The last two nights I have been in the process of tuning. Last night I was trying to lean it out and get some more power. Well my 02's are now at .92 before 4k and .94 after 4k. I believe that that is about perfect as far as 02v goes. But, my timing is still at 20-21 by 7k and my EGT's are only at 1450'. My LTFT is reading -11% down low and 0% after 4k. I think I can lean it out more and just ignore the low 02 readings but what do you guys think?

Yes, first of all, those 02's aren't lean. Lean in terms of dangerous is below .87 Those are merely what most people consider optimal, so leaner then that is penerally not good for making power. Go ahead and try it, but I doubt you'll do much better, thats fantastic timing

Tune for timing, not O2. O2 only gives u a ballpark idea of whats going on. So lean up that WOT lil.
