Got the plots/graphs to Corey--he hasn't had time to really get into them but did offer a few guide lines--

At cruise in closed loop it should tune to arond 14.7

on accelleration/wot---12.5 up to peak torque area then lean to 12.8 at WOT top end(about torque peak going up towards peak hp)


your picture doesn't show enough of your o2 adapter to tell if your getting any reversion into the exhaust tip---this has been an repeated area that we see--best is to weld a bung into the header merge area
