    I'm waiting for the factory warranty process to be completed before purchasing the mountune 215 kit, but it occurred to me to ask those who have already installed them......

    Is there a decrease in fuel economy? .. How much? .. Has anyone done before and after testing?

    It's been 4 days since having mine installed and I'm getting 6.8 liters per 100 km while on a "road trip" . The most expensive part has been a speeding ticket haha.
