The loyality will depend on just what you are asking them to do, how much risk they are taking, and (obviously) how much of a reward they get out of it.
Getting a go-gang to do a drive by harrassment of a location isn't going to require too much lotality or reward.... this is something they do all time, has little added danger to their usual routine, and is not out of the ordinary for them.
Getting that same go-gang to get into a long, drawn out, stationary gun battle with Red Samurai is going to take a very high loyality and reward! The go-gang is not in their element (highways, roadways, moving targets) are engaging a superior enemy with superior firepower, and there is a huge risk of death!
This concept is going to require a lot of talk with your GM to hammer out the details of just what a contact is willing do for what, at each loyality rating and is not something you are going to get a universal agreement on
