Experience form racechip on the grande punto 75hp 1.3mjet

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 !

Cabbage to me on a rexton has shorted the 5 volts fulminando the ecu the engine you are I am too well lucky me

Damn what is that ? serious damage .. But probably your was I don't know a faulty module but after my experience I can say that even if the module does not have problems in the long run destroys the pump and the injectors, and even why? unlike the map, the form and function of the gi? to a minimum with increase of pressure in the rail absurd .. different Speech and if you mount it on the injector pump, why? acts extends only l injection without affecting the pressure of the fuel !
