engineperformancechips.com Had me try different ways to make the engine chip I bought work only to take me beyond the 30 day return policy. Internet

Bouoght the engine chip in Dec. 2013. It did not work so after trying all the steps the company said to try they sent me the newest device that was supposed to improve fuel economy and performance. This also did not work so they had me try different programing steps again with the new modle. Nothing worked so I called them and was told that they only had a 30 day return policy. I explained to them that all this time I had been following the instructions they gave me but they will not trfund or replace the unit. Big rip off,. The junk just does not work. also the customer service really sucks.
