    o2s lean out where your describing. Put a pressure gauge on and go for a run. You have a wideband?

    Thats what i thought, last run it did, i richened it in that area in the VE and same with the PE after 5200rpm and it made absolutely no difference.
    My wideband is playing up so no wideband.
    Its confusing because it is a 2Bar OS when it previously had a charger on it and the VE table is still in 200kpa format

    Std fuel pump and still has the 60lb injectors in it.
    Also has LS2 heads on it.
    May be a fuel delivery problem
