If Mike Troyer did the tune, probably not - he tuned it correctly in the MAF curve so any airflow increse will automatically be compensated for - remember, the exhaust will help to increase airflow to the other side of the engine and the MAF measures the mass (weight) of the air. Mike is a friend of mine and he knows what he's doing. So as long as your MAF doesn't peg, you are probably OK. That said, what I'd suggest is - since sometimes things don't always go the way they are supposed to go - is to at least take it to the dyno and check the A/F and log it to be sure the MAF is still OK. If it isn't than have it fixed in the tune.
