I have Torque pro and Dragy, and when it comes to 0-100 / 1/4 mile times the dragy takes it hands down, but that is if you have that decent flat surface to do your tests, otherwise it shows as invalid if it is too much of a downward slope,
Where if you use the Torque pro, you can drive down a mine shaft it will still give you your 0-100 time as accurate
