Was talking with Deb at PJ's today about the 140mph mod that is out there and she also informed me that they sell the 170mph. She said that it matched the other gauges in the car when it is installed. I would have to say that,most likely these Deloreans have the 170mph mod installed. Give me a call Darren, I am already trying to take off work Saturday....maybe I can join you. Robert Starling Vin#05252
