What boost was it running before all of this? Is this the first WOT run with the new turbo/manifold/wastegate setup? I'm betting that the spring is not right in the WG. With an open exhaust, and the port you have that engine will produce a decent amount of boost. 15psi is way to much on a stock S5 turbo though - so I'd avoid WOT runs until you figure this out...
