Fuelly Forums - need best strategy for testing ne gas saver

Hi guys! I am a Canadian currently living and working in China and involve in sourcing of auto components from Taiwan and China. I recently came across of new fuel saving device based on ultra capacitor.I am always very skeptical about such things and have seen many of so called "latest and innovative" devices but as my knowledge non of them really worked.
But this saver grab my attention since it came from trusted scientific lab in Taiwan and it was introduced by good friend.
So I decided to have a closer look and check it out by myself and on my car first.But it was hard to measure fuel saving in city traffic so I decided do test at independent lab in Guangzhou on 2,5L Buick with 32K mileage.When I got my test report it was shown saving fuel around 15,35% and emission cut HC：-25%，CO：-36%，NO：-5%.So not bad result at all!!!
I understand I need more testing should done by well known agencies and labs but it costly and my finance sources are limited.Does anybody know how much cost similar testing in US by EPA for example.
I need you critics, advices and suggestion how I can start promote this device or may be I just should dump this idea after your positive critics.
