I figured as much. When their high tech demo you always see is a couple of 7-up bottles duct taped together! Why not a real demo of the actual product in action?? It's probably another of those "as seen on tv' products.

I can't change my driving habits!  Too much testosterone dude!!

I probably get 6 mph city and 4 or 5 highway on my K5 Beast.

I'm not sure yet, but I think my Holley 750 cfm double pumper may not have been the most fuel economical choice for my GM 350.

If I wanted great fuel economy and great gas I would by a Geo, and eat at Taco Bell all the time!!
