If your using the stock ecu programming then I wouldn't go anymore than 13 psi. There are some good tuners that have spent many hours tuning the fuel and ignition maps to allow more boost, like 18psi. In doing this they can maintain reasonable peak cylinder pressures and still allow more boost. If you just turn up the boost without optimizing the fuel and ignition maps then bad things will happen. I have run 18-19 psi in mine for over 10k miles with no problems.
