Sure it is. But you have to realize you are off the map for both airflow and manifold pressure. After the MAF maxes out you would need to start artificially raising the PE to keep adding fuel as RPM's and boost go up.
Having said that it's not a good idea. As I mentioned you cannot meter the airflow after ~5000 RPM's. It's better to get a 2 or 3 bar PAP and go with a multi-bar speed density tune.

The MAP will obviously max out as soon as you get into boost. I would SWAG the MAF pegging the airflow and frequency limits @ ~5000RPM. My old '99 with an A&A P1 kit maxed it out at ~5500 but I was only making 7# so you'll likely max out earlier.

My tune was recently redone went to speed density and I am not looking back. My car is running much better in SD in both drivability and up top. I don't have dyno numbers to know if the new tune makes more or less power.

Add a 2bar MAP sensor and go SD. A little more work to dial in the tune but worth the time and peace of mind.
