Valve Spring Help

I have a G5X2 cam 2.08/1.6 valves and 921 springs. I put the car on the dyno today at Xtrem Motor sports and acording to them at 6300 rpm there was bad valve float. The springs have the correct seat pressure. I thought the 921 were good springs.

Are you in AZ? I have the 921's and the X3 and the springs seem to be doing a good job. How can they tell if there is valve float on the dyno?

What's your name? As for the curve, that sounds weird, not sure what you can do but take the cover off and check them, you have probably already done that anyways. What was the power at when it went flat? Did it do it repeatedly?
