Im thinking about buying one of these from zzp but i was wondering since i dont have the big three in my car yet will the smaller wire be able to handle it? my next question is should i get the big three first? i cant really do both at the same time do to money so i was just wondering if the stock wiring can handle the voltage booster or if i should just do the big three first.(im aiming to get my car to get 30's for gas miliage and im at 26.5 now and i read that this could move it up as much as 2 mpg) so what do you guys think?
