The most important features to tuning in a piggy-back system is the ability to manually adjust Air/Fuel Ratio's and Timing. Having the ability to modify A/F ratios and Timing enables a tuner to maximize a vehicle's efficiency both power and performance wise.
Alternatives to Piggy Back systems are Stand-Alone systems, which replaces entirely, rather than work with the car's standard ECU.
There are pros and cons to both.

It seems like the Stand-Alone would cost more since now your replacing both the Standard ECU and this piggy back right? So what are the pros and cons to both, and when should someone start looking to consider either a piggy-back or a stand-alone?
