any experience with Pit Proven Performance (3P offroad)

I called 3P to see if they would tune up my turbo rzr 900xp on the dyno and while they were in there adjust the clutch appropriately, they said it would be between 300-400$. My question is; is it worth it? have any experience using 3P for anything else? I have no doubt they are a good shop, I’m just trying to justify that price.
