differential fluid leak on 340

So I have been running xHp Stage 2 trans tune for the past few weeks, absolutely loving it. Took my car to the dealership today to get a brake screech issue looked at and they also found a differential fluid leak near the front. No idea what caused it, does the differential sit lower to the ground and more prone to get hit if go over a harsh bump? I'm guessing it was either that or something related to the line pressure increase on the transmission caused the leak.
