Hey mate,
I think this is written elsewhere but stock is about 17psi, a few higher than the rex due to the smaller turbo.
Going up one or two Psi should be fine. But i wouldn't bother. The main restriction is the ECu. Get a retune to unleash the powers.
Much better to just get a dump pipe and a tune and leave the boost close to stock.
But thats my 2 cents worth, other people do different things.
