thanks for your answer.
I have contacted Paragon but still no reply, so i try with apple communitie.
I hope that someone using a fusion drive and bootcamp and camptune success to resize his boot partion without detroy and recreate it.
I hope if this person exists can help me to resolv my problem.
THe official return from Paragon support is that camptune does not yet compatible with fusion drive.
So Size correctly your bootcamp partition to avoid spending hours in reinstallation or backup and restore.
When a new version of camptune will be release the support will inform me and and will post a message in this forum to inform the community ...
Have an happy new year !!!
