X2.
Pump gas doesn't usually equal very high boost on a dsm motor. I'd be more focused on what kind of power goals you have than how much boost you want to run.

Last summer on e85 I ran around 32-34psi daily through my stock 6 bolt and had boost spikes of 38 at the end of the year on the dyno. Also probably have around 30 pulls at 30ish psi plus a 75, but that was with an amazing tune from Shane @ DB.

Either way I would take it over to Shane @ DB so you can get the most out of it as safely as you can.
