1406 4 pole 4600kv

Try this, hold the spur and spur side tire and try to turn the left tire. If it turns your diff is shot. If it doesn't spin your diff is good and the problem lies elsewhere. Could be any number of things such as balance, preload on your shocks etc. Asphalt is not really a good testbed for offroad setups IMO. Tighten up your slipper and take it to the track for testing. Honestly I think your just diffing out due to the light oil or grease you have in there. I run 30k in my flm diff and it's still a bit light but gives me the best balance for my driving style. Kinda tough to work with the stock diff but try to find some of ofnas diff grease in 30-50k. Should really help with all that power your 1406 is putting out.
