this might be good upgrade or no it depends, without good remapyoull get only sound from the engine and less mpg
i did similar thing on my 106, 1.6 8v engine had small inlet and it was oplastic, but 1.3 rallye had aluminium and it was much bigger, without remap i got only much better sound from front and 12lit / 100km (originally was around 8-9lit/ 100km) but it wasnt so much faster
