im not saying this product works but voltage stabilisers do work in producing power,
im not saying more power= better fuel economy.
but take a look at these, i plan to test one out when i can get a hold of or make one.
some results\

my internet is crapping out so will post more tests later
they make more power in the lower rpm range (hypermiler central) like i said i plan to test these out for you guyys one day in the future and see how we go, i think there is something to them. (feel free to prove me wrong i like hearing other peoples opinions)
