Wp cone valve setup

How’s it going everyone. I need help with my cone valves, so I will just jump into it. I purchased a used set that was basically brand new with 8 hours on them. Their the newest version, small axle with black uppers and lowers for my 2019 ktm 350xcf. I immediately sent them to powerband for a revalve and service before I road with them. I had them setup for b class off-road racing, I do jday off-road. When I got them and road with them for the first time they were incredibly stiff, so stiff that I was only using a few inches of the stroke. When I talked to the local suspension guy in mass REP, he said the 390cc of oil I’m running is way to much. He had me drop it down to 350cc now their actually working ok. To be honest I have been doing clicker adjustments and I’m getting a decent setting, but I’m not really impressed with them. I heard so much positive feedback that they seem to be a letdown. Tony at REP said for new England woods powerband makes them to stiff from the few riders that have come to tony for help. He uses a much softer setting. Should I have him do a revalve? Or are they just not as good as everyone says. Is their other adjustments I can make? I was really expecting a fork that is plush throughout the stroke, but that also has good hold up. It has great hold up but when their is not much plushness or comfort. It’s better when I lowered the oil height. But if this is as good as they are I’m pretty disappointed. Any feedback is appreciated.
