    What supercharger wheel does Dean recommend with that Stage 3 tune?

    Did you find a place for the Orange o-ring?

    For Riva's Stage 3 yes. For Deans Level 3 tune no. Dean's Level 6 is for the high boost wheels.
    Dean's Level 4 is comparable to Riva's Stage 2.

    So Dean’s uses ‘Level’ to describe the increments of tune, not Stage.

    Are the Dean rune Levels and related equipment requirements posted somewhere?

    Last week, the ski was running in the 8500's rpms.
    Today rpm's were bouncing off the 8800 limiter @15psi and afr's were lean in the high 12's to 13 at wot.
    You might want to check your afr's with the cooler weather and running kanaflex.
    Huge swings in water temps and air temps play havoc with tuning. I compared a datalog from my maptuner in July and another in September with the same stage 3 17psi 8900RPM tune. You can see that i'm running leaner in all RPM ranges so it's something to keep in mind if your are pushing the limits in warmer weather you might be in trouble when it cools down.
