O2's

[tc86gn]

I am kind of new to these cars and have got about 2000 miles on a fresh build that seems to be running strong.
Right now I am running 45 lbs line of fp.19boost w/0 kr. At WOT o2's are at 850 range. I turned down fp 2psi and then got 2 degrees KR and o2's stayed the same. What do i need to do to get these numbers down. I turned fp back to 45. car runs great but the o2#'s bother me.
I feel I am getting closer to getting the most out of this car just need to do a few more things. What is the potential of this setup?Never been to the track before.
Any suggestions appreciated.

I assume 93 octane fuel? I assume a fresh O2 sensor?

If so, I really don't think you have a problem. 19 PSI with 0 KR is a pretty good state of tune, even if the O2's are approaching 850.

You can walk the O2's down to the 760's to 780's with race gas, but the pump stuff often likes the O2's in the 800's.

I run 18 PSI, with 810 to 820 O2's with 100 Octane fuel.

Yes it is 93 OCT and a new heated o2. I think i am gonna turn up the boost to 20 and check it out.
