hello,I do not know well the operation of the add-on module that you install on the accelerator pedal, but I believe that he will do only the function of making the car more nervous on the basis of the position of the pedal, and then does not increase the power but only the shot, while the maps enrichment and acceleration on the edc 16 have a function of enrichment of diesel, therefore, apart from the shot, the machine becomes even more powerful.
