I actually use a laptop for tuning, but for every day driving it would be nice to have a normal gauge to look at instead of the ZT-2 display that is hard to see in sunlight and sort of mounted out of the way. Also if I can get this and the boost together I would jsut put it in the stock boost gauge, and get one other gauge stock mounted beside it with oil pressure/temp.Have you looked at a Palm running the pocket logger hooked up to the Zeitronix? I liked this and I could log on the palm and then hook the palm to the PC for upload. Also the warning trigger was a nice option.
