If its a generic mapped ecu board then by fitting a larger maf it may not fuel correctly if you have no access to altet the map.
Best thing to do is get it on rollers and see what boost you can safely run and also how it runs with a larger maf fitted.
You qint get more than 340 with the stock maf and thats assuming its functioning correctly, think if i were you i would try a GTR35 maf on it as they have scope to read a far greater airflow.
The car will still run more than 340 on stock maf but the issue is that it simply can not calculate the volume of air flowing through it so then the ecu plays a kind of guessing game as the readings it recieves from maf will be inacurate which is when things become either way too rich or lean at certain points in the generic map which has been loaded
Hope that kind of makes sense to you
