    really? that sounds more like XX numbers rather than XXX.

    Ya I just had an xx in my ski, was seeing over 14 at 8400. I never checked slip on the new charger, I should have, I can tell its a bigger wheel just by how often u hear the blow off valve compared to the xx, on my first run of the day I will see 14 psi once it gets good and warm I can't break 13. Low and mid feels much better than the xx did though,
