Ok I am thinking about a Gtech( I think that is what you call them.) Since I saw buzzes video of the G teched Titan. I didnt know it was something that just stuck to the front window, I thought It was much larger than that. Im pretty dumbed on this subject so I am looking for someone to tell me where I can get one and how much? Also How easy are they to hook up? Does it just tell you how fast in the 1/4 mile and speed or other good info about what is going on in the engine? Is there other brands that might be better or worse? Can it easily be transfered to another vehicle? I did a search but the reading is extensive to find out all the info. Thanks!!
