Hi does anyone know what psi the turbo should be running at. 
I am thinking of fitting a boost control valve and guage and was wondering what I could raise it by before needing to alter the fueling  |

It might be worth getting a boost gauge and an exhaust gas temp gauge as well  You'll know what your starting at, if the exhaust gas temp gets to hot then you'll kill your turbo.

My 3.1 is running 17psi (VI95 turbo) as stock.

Where are you measuring that ? At the wastegate - or at the inlet manifold.
I've just fitted an accurate gauge to my 3.1, and I've got 10psi at the manifold, but I'm thinking thats a bit low, as I've fitted the FMIC and not would up the boost yet to compensate

Inlet.
I just fitted a fronty intercooler and am now getting 15psi. But your cooler and pipework is bigger than mine, and my gauge may not be 100%...

2psi loss for a FMIC sounds about right
I had a little TIM turbo gauge on there, but couldn't read it easily. So on Saturday I dropped £30 on a big industrial gauge, I'm pretty confident its accurate  |
