Oscillations in fast forward flight - PID issue or filtering problem?

Getting visible oscillations in my FPV feed during high-speed forward flight and punch-outs. The quad feels stable in hover and slow maneuvers, but shows high-frequency vibrations when I push throttle or go fast forward.

Current setup: 5" freestyle, 2207 1860kv motors, 6S, Mamba F40 ESC. PIDs are P30/I50/D22 which seem reasonable. Blackbox shows some noise in the 20-100Hz range during these maneuvers.

Is this typically a case of P/D gains being too high, or should I be looking at gyro filtering first? Motors don't feel hot after flights. Props are fresh Gemfan 51466.

Should I try reducing P by 5 points first, or dive into filter tuning with PIDToolbox?
