RE: What MPG and HP increasing devices NOT to buy!
I read the article as well, and didnt know about these devices until i did. i went on ebay to see if the lisitngs had any response to the article, and of course they didnt. however, i did browse the feedback and some people are claiming they work. is this the seller logging in assomeone else leaving feedback? im a little confused. could it be that these devices work on smaller engines?
