Is this normal at high RPMs?

I'm just wondering if this is normal, when I'm hitting 6000 RPM, VERY shortly after the car lets out a HUGE power drain that pulls you forward a bit at WOT. I'm worried the valves are floating but I'm wondering if others have this problem and whats a way to fix it? New valves/springs/retainers? New Camshafts?

Sounds like fuel cut to me.

I'd suspect a boost leak, perhaps.

I also had similar symptoms with a set of plugs that went bad (overgapped) much more quickly than I expected, though the stumble was much less pronounced.

My 14b never fell off at higher RPMs. It held 18psi through 7200rpm every time.

In this cold weather, it could possibly be the MAS reading too much air. This would result in fuel cut.

But honestly, how is your clutch doing? When my clutch started slipping it would hold strong in the lower RPM, then the car would fall flat on its face in the upper RPM around 6k at WOT. Might want to check into that.
