Does it seem to be better or worse at an idle?
Are you open to trying a trick to get it to work? It doesn't require any parts.
Something I've done on a number of these variable displacement compressors is swap the scroll valve in the back of the compressor around backwards. This makes the compressor work like a non-variable and seems to solve all of these on gain off again issues we have had with them.
You would have to evacuate the system, remove the scroll valve, flip it around and put it back in with the big end towards the compressor. Then recharge the system and see how it does.
