What sort of wastegate do you have? You could possibly set the boost lower for normal use and have a (horn?) button to increase boost when you want it. Tee into the air tube that goes to the wastgate from the plenum, and run it too a small 12v air solenoid (available from hydraulic and airline specialists) Wire it to open when you push the button, so that the boost that is trying to open the wastgate escapes. You don't want too much to escape or the boost will not be controlled at all. So fit a 'jet' or needle valve into the end, and leave this pipe open to atmosphere. Now low boost is as set up normally and high boost is as you set the needle valve or jet.
