AI aircraft too fast?

Hello friends,
I like to fly with all the AI traffic in place, especially the Project AI stuff. But when I'm on final, it seems the AI traffic overtakes me and gets the clearance.
I usually fly 737 and come in at about 170kts until I get closer (and then drop to 147kts for the landing). But doing so, AI traffic seems to fly right past me.
Am I going too slow or is the AI coming in fast?
