just been on e-bay and theres an item from powermaxx claiming to increase punto bhp by 7+bhp.it does this by trickying your ecu into thinking theres more air coming in at a cooler temperture.Does any have or know someone who has got one of these powermaxx on there car and if they notiched any think different happing to there car.Also seen some magnetic box that goes round your fuel line that removes all the metal that is in the oil, flowing through the pipe to make the car run better has anyone come across a gadget like this before and do they work.
