Review on 🚗 Volvo Performance Chip/Power Programmer - Boost Fuel Mileage, Save Gas & Increase HP by Kevin Stephan

I installed this on my 2009 Volvo C70, the instructions were very helpful, also it didn't say which wires to connect so I chose the middle two wires and it worked great! This chip is not a scam, it really works! Just be prepared to disconnect the battery and connect the two wires and you'll see amazing performance gains and fuel savings! I couldn't keep my foot out of the way after installing it and still saw a 3mpg increase! Also, I emailed the company and they helped me a lot by telling me what the chip does to the motor and how to install it! Excellent customer service!
