Velocity for .25 Impact

I just got my Impact in .25 caliber and the regulator is adjusted to ~140bar, hammer spring on 3.25 bars, and speed 1 it's shooting 25.4gr JSB King's at 895FPS. I feel like that is really hot for those power setting. I'm planning on turning down the reg pressure so I can have more fine tuning adjustment abilities. What type of settings are you guys using for your Impact?

I feel like I've seen a thread like this before, but everyone's always adjusting things so a new one won't hurt.
