The stock Garrett I'm sure is good for 2 bar...easy. If only I could deliver as much fuel as is needed for that...

this so far is the most grounded/practical response. well except for the part about a tiny garrett doing 30 psi lol. i wouldnt want one of those above 20, probably just hot air above that anyways.
diverter valves dont make more boost. they make the same boost sooner but even then its at the expense of having more drive pressure. the easiest way to get more boost is to trick the wastegate. either mechanically with a hole in the boost elbow or electronically with a controller as stated above.
