"What you have there is a RG-240 (repair grade). This dynamometer was designed specifically to run transient emission test cycles and pretty much that is it."
From Mustang... Just FYI. I sent this ad to a friend who was looking for a used dyno (AWD) - he sent an email to Mustang to see if this one could be upgraded to AWD and that was the message they replied back with. Not saying that it's a bad thing or anything, just wanted people to be aware. I honestly didn't even know there were different grades of dynos before this
