Hello AquaTune, I own an automotive repair center. Recently we had a customer whose vehicle would not pass emissions because it was smoking so severely that the emissions testing center would not even insert the probe into the tail-pipe. After installing an AquaTune unit on it, and allowing it to run for 45 minutes, all smoking came to an end. The vehicle was then taken back to the same testing facility and, in fact, the same people and they were absolutely astounded at the difference. The vehicle passed below standards and totally proved my skepticism wrong! I was also amazed at how it cleaned up the rings. I now plan on using this device to take to other shops and dismantling yards that sell used engines. Thanks for both myself and my customer,.
