The shop where I bought my FAST system in PA spends a good part of their week educating and supplying tech support to cheap car owners who bought their units over the internet or through mail order because they got a deal on them. The reality is that these consumers have no idea how fuel injection works or how an engine works so they can tune it properly. So it turns out that these self proclaimed "know it alls" need tech support but don't want to pay for it. This shop owner gets extremely irritated with theses dealers that are selling the units at a discount because they can't supply the tech support or actually tune the units either. Maybe if some of the readers of this forum would actually spend the money and pay what they are suppose to pay for these units, they would not have to spend all their time on this forum trying to "fix" their problems and more time driving, racing, and enjoying their cars.
