The Powerplus unit eaze of installation amazed me. The functionality and performance is what really ROCKS! I don't think one will find another product locally with the all the benefits of both unlocking the performance as well as offering fuel economy options. I tested all the modes of driving and can really switch my mode of driving with a click of a button ,depending on what I want. What sets POWER+ apart from many "pedal box" units is the setting/adjustment of the intensity of each mode of driving the user can select to personalize your driving style.Really Amazing product,definitely value for money and recommend this unit for everyone. From economy mode to sport mode,this unit has benefits for every dring style.Dont delay ,buy TODAY!
