We are currently searching the market place for fuel enhancing,and fuel saving devices for gas and diesel engines for both personal and commercial applications. We are located in Canada and have looked at several different variations of devices on the market. We will only be looking at samples for test results until we locate a proper working model in to which would falll into our market place with the desired results promised by the manufacturer. There have been many out there that have said that they work with savings up to %40 with little to no results ,therefore,we are erring on the side of caution as this is to be passed on to our customers...and we have our company out there with our client base and need a reliable product to fulfill that gap. Thank you for your understandinng and patience. Sincerest regards Duane Bohemier
