I have one on my Silber turbo setup. It was very easy to load the map for the turbo setup and it does have great monitoring abilities. The problem is that the screen is next to impossible to read while driving the sled. Plus, it's not in a waterproof, impact proof case. The problem I have with my turbo setup is that I can't adjust fuel settings on the fly. So once a map is installed, that's what you are stuck with. IMO, this is one of the reasons some guys had issues with the bog on the Silber turbo setup. I like that you can easily switch between maps and going back to stock. The monitoring is really robust too. I really depends what you want. I'm thinking you are looking at using the BD to update a stock sled. I know BostonRacing was offering this package. I would be interested in how it works on a stock sled.
