Dyno Spikes?

I just got back from the Dyno. What could cause spiking from 3700rpm to 4800rpm? Heck, I see a 30hp spike from 4700-4900rpm. A/F started at 12.7 and went to 13.1 WOT. My base boost is set a little high at 6.5psi and the boost control valve has been buzzing louder than normal lately. I showed 237 max hp and 257 for torque. I am planning a 3" DP and a Nordic Stage 3 ECU next.
