what do you tuners shoot for when running a setup such as mine with 8-9 lbs of boost? What air to fuel ratio and what 02 readings?
Does it just come down to knock? In other words, as long as there's not knock, then lean it out?
Just curious. I ran my car with the o2's a little low after some changes so I think that I need to richen it up for a little more safety net. It ran a little richer in the mid rpms and a little lean up top, but up top it ran cleaner than the middle rpms. Knock was almost zero up top.

My understanding is that if you use alky or methanol it will cause the readings to look a little different .... I was running around 880's to 890's if you are too lean the power will flatten out which kind of leads me to believe that is where you are at now...
What are your injector times at WOT ?
You may need to just see where the engine seems to pull the best... and of course look for knock...
