Just curious, Can you have too much octane to where you will see a decrease it performance? Say 20-22 psi, I've heard of some using c-16(117 I think), and some using 110 leaded. I was told that the c-16 is too much, is that right? I would rather be safe than sorry. Do any of you do a blend, what is it?

It all depends on how aggresively the car is tuned.

If you have some majorly tweaking ignition timing, then maybe it won't be too much, at least not at 22 psi.
