5.1 Import scale not right

So I trying this new 5.1 and when I import a Mesh it is ginormous. I use 3ds max to make my models and I draw in cm. I have always imported at scale 1 and everything is fine. when I try bringing into 5.1 it is ginormous and I havent changed anything. I even dropped the scale to .03 and its still like 4 times larger than should be. is there something new in 5.1 I need to set as it works fine at 5.0 and below?
