    Running at a hpde today I noticed my afr was all the down to 9.7.
    I'm running the Cobb stage 2 map w/ intake and intercooler.
    Is this normal? The only thing I have to compare to is my Evo which only dropped down to 10.5 or so.
    Thanks for the help!

    I would start by looking for boost leaks/intake leaks..... usually when running super rich it's near the intake

    The ecu will dump fuel to cool the engine/oil when it detects overheating or excess knocking. Sounds like normal ops to me when running the car on track.

    Was this a Min / Max display value or you saw it happen in real time?
