If you don’t have one yet then you are missing out. I love this thing and the way it makes your car feel. You don’t get more horsepower from it but it sure feels like you do. I can’t really drive my car in sport +4 the pedal is so responsive, I look like a beginner driver especially with a manual transmission . Go get one, once you drive with it for the first time you’ll be amazed how much pedal you weren’t getting and you will wonder what took you so long to get it.
