Wow, thank you so much for your input! Very good help.
I know this question is old, but I thought I should answer it for anyone else with the same question. Yes they are know for working on AWD vehicles. Subaru's, GTR's, Mitsubishi's, etc. They use the Dynapack system which connects directly to your wheel hubs. Way more accurate than a roller type system like Mustang dynos as long as the Dynapack is calibrated properly. Shawn's has been tuning my 2015 Subaru Forester XT since 2016
