Tuning boxes work on the basic pricipal of allowing for more fueling into the cylinders. In diesel cars you can add more fuel and make sure there is more air to burn it and the system works.
In Petrol cars other than fueling you need to also look into ignition timing etc so the procedure is more complex and requires a complete remap for the car to run properly. Does not mean you cannot remap a diesel, ofcourse you can and you can get a lot more power out of a remapped diesel than a tuning boxed diesel becuse you can change more parameters and get the best out of it.
