Tune it for 15 during your tuning session so that the ECU has the full capabilities it is supposed to, and if you have an electronic boost controller, run 10psi for a low boost mode and 15 for your hi boost mode (a lot of electronic boost controllers typically have two modes).
That way you are not beating on it for regular driving, but if someone wants a piece, you can click the high boost button and you got 15psi.
Remember, with great boost, comes great responsibility .
