quick question....97 f150 5.4L...ive been seeing a lot of advertisement for these electric superchargers??? they are only 70 bucks and claim to have hp gains from 20-50...just curious if anyone has one or knows of anyone who does and if they even work???

 

A guy mentioned that he had one and was getting 18 MPG. Where did you see the advertisement?
