Jason faced that above 24 psi and was loosing boost down track and at high rpms on the dyno. so he replaced the 8 rib with toohighpsi 10 rib system that I'm getting. I don't plan on ever spinning it that high but I love the way it looks.
KaTech has said their Maggies stay around 18-19k rpm. Kong said it's Ok to go to the 21-22k range.
