Do programmers (hyper,diablo,suprchps) come with preset gear ratios and 14 degrees timing advance, or do you have to tell them what your plans are for the car and they program it accordingly?

If you buy the Diablo Predator handheld tuner, it comes with a performance tune that replaces your stock tune. This performance tune advances your timing, changes your air/fuel ratio, and improves your automatic transmission. Beyond installing the performance tune, there are parameters that you can adjust, e.g., axle ratio, rev & speed limiters, spark advance, fuel base, shift firmness, etc.
