engineperformancechip.com lied about the product,it was a fake Internet

I purchased 2 oxygen sensor chips for my car they say it will boost your hoursepower.   Well they didn't work so I  took one of them apart and all it was were two wires going through a hollow tube.   Which means I could have just put two simple wires in place of their product.   Ita a scam and I emailed the company and told them about my findings,  but as usal no reply.  And in this day and age I can't just throw away $80.00    I waited about one month to see if they would reply or refund my money and still no answer.   So I just want to let people know that if you buy that product from that company you might as well flush your money down the toilet.
