I have the fastace 2nd gen forks and the fastace 66RC shock. I'm 6'4" 230lbs. I have 150-160 psi in the compression leg and 70-80 psi in the rebound leg. I have the compression clicker maxxed out and the rebound clicker is about 1/2 of the way in (maybe 6-7 clicks I think). I really like the forks. They have a little bit of dive up at the top of the stroke, but once they move about 1-2" into the stroke they firm up and get nice and stiff yet plush.
As for the 66RC shock, I love it. I'm a little over 1/2 way in on the compression and a little less than 1/2 way in on the rebound. It feels very similiar to the DMN shock that's real popular now but the fastace is more adjustable. I've shimmed mine (both eyes) with 1/8" poly washer on each side to compensate for the lack of the hiem joints and my big fat ass. So far it's been taking a real beating and holding.....not to mention, it has a great over-all feel to it.
I rode a full size track on Sunday with my mini and I was able to do most of the jumps that I do on my 450. I only have about 20 hours on the suspension, but so far the fastace stuff is no joke.
