    The 13/18 SXX solas should be depitched ~ 1mm on trailing edge with a stage 2.

    My power seems to vary a lot as well depending on the day. I think an intercooler might make things more reliable on any given day.

    I have a 13/17 and just turned 8350 in 90f @ 750 msl. Try depitching and get those rpms/boost up.

    I don't think the intake grate is doing you any favors either.

    You should not need to depitch the impeller. I have a 2017 Rxpx with a stg2 tune, Riva CAI, the FA is removed from the manifold and a 15/18 SXX. Just last week I went 78 mph @ 8240. And that is in 92-93 temp with 90% humidity!
    First and foremost, PUT THE STOCK INTAKE GRATE BACK ON!!!!!!! The stocker is the fastest. You say you have fresh oil change? Who did it? Check the level. Always start small and then work your way up.
