None of the stock gauges on my SS/GT Mustang work so I need a speedometer if I'm going to try to street it. SpeedBox on my iPhone works for that. It uses either GPS or the accelerometer in the phone to read speed. Pretty accurate. I have Engine 2 LBox for determining static and dynamic compression ratio based on a ton of input fields. It helped me pick a cam but the fields are hard to enter on a standard size phone.
