You will notice a difference, but it will probably run worse. Keep your ECU stock until you have a good reason to have it tuned. This isn't Gran Turismo where you pay 100 credits and get 12 hp from an ECU chip.
For a stock motor, there is no other ECU that will make it run better than the one you already have.
