Hmm, could be a fuelling issue then, if it was only making 8psi even on standard fuelling you'd almost definitely see smoke. How does the engine actually run? Does it feel lumpy or anything? Struggle to idle?
You could try turning the fuel up a bit and see if the boost increases. Basically if it's burning clean on boost, your turbo's producing enough air to burn all the fuel. If there's not much fuel going in, there won't be much boost made.
When you boot it, does the gauge pin at 8psi for the whole rev range or gradually climb to 8psi?
