On the website Volant does not make the powercore for my truck. i found one that almost the same as the one that comes with and ordered it. i put it on and didnt do that much in power or gas mileage. after about 1000 miles of driving with it it improved the gas milege a lot more and im very happy with it. i recomend it.
