Based on the prior replies, maybe just a new O2 sensor, connect brown wires and double check base mixture may be all that needs doing.

Yes, the DME does a decent job in closed loop mode to help correct mixture but the DME ignores the O2 and switches back to open loop under these 2 conditions:
- above 50% load at any RPM
- above 5120RPMs, regardless of load
so you can't depend on the O2 signal to fix/correct mixture for all running conditions. This is why it's important to have mixture set/checked from time to time.
