Hi guys I hope that my experience can help someone of you...a few months ago I bought the racechip module paid 300 from the official website and I installed the module is already calibrated from them in the grande punto multijet a friend of mine with just 50,000 km...the car was totally changed, made better, it consumed less and a little smoke but after a couple of months, the morning cold went to 3 cylinders for a few minutes then I tried it without the module and the problem spar?..after this experience, I realized that the form ? nice pero in the long run seriously damage the injectors and the pump, in fact I also found the chips in the fuel filter... !! I'm at the point, it is better the map !
