I would highly recommend Tunit, great customer service. Both the Optimum Plus and Power Pedal have made a considerable difference to my car with regards to acceleration. Considering I can change the settings on the Optimum Plus, I have never actually wanted to and have been more than happy with it on Sport +. Glad I bought these instead of getting a re-map as I can unplug and plug in whenever I want; it’s great!
