Why would you want it to go faster on takeoff? are you street racing? vehicles are intended to be driven with certain things in mind, slower take off per example means is saving you fuel hence environmentally friendly, specially on a V6 that is great, unless you are racing of course, but that is another thing you should keep in mind. You did buy the vehicle because is sporty, but face it as great as it is, is not a race car. Be happy that you can enjoy a great new vehicle, and remember that you had a chance to test a few others before you bought it so you no one else to blame but your self.
