This is excellent tune. Very clear instructions and easy to install. Make sure you have a good laptop that can get the ez flash cable to work. The engine tune is great, the car is more responsive. The transmission makes quick shifts and holds the gears much better. The eco mode is very great when you are cruising around town or highway. Also, make sure you have the cruise control on with the light on, that way eco mode is engaged. The sport mode is the fun part. Aggressive response and you have to watch your foot pressure on the accelerator. It gets up to speed fast for great passing power. Great investment and to add the tune does not compromise your alarms and keyfobs, so everything works as usual. Thanks trifecta.
