U172. Very easy to install. Entered the 87 octane performance tune into my 2005 V10 Excursion. Unable to determine the effects sice it was just installed. Unit lacks documentation on the operations, I am not sure what each tune will do and what is involved in a custom tune. I am somewhat disappointed to learn that there is not a tune for towing for the gas engines. That was one of the reasons I bought the tuner.
