Rpm switch comes on with the lower rpm setting and off with a higher setting. Turns out the switch was set to "on" at 7200 and actual shift rpm was 7450 on the data logger. So my concerns about too much rpm were not as bad as it appeared by watching the tech. Once I widened the rpm window to 400 rpm the system worked fine. When the shift occurs the rpm drops below the 7200/7600 rpm window the switch turns off again. With the switch activated, it provides a ground for the airshift solinoid, shifting the trans.
