just got one of these off Amazon and wow.. no more slow unresponsive pedal where you press it and nothing happens. 

It instantly pick up and pulls. makes the car feel more powerful. ( it does nothing to power ) but very impressed. 

ive had the car and done 20k miles and hated it everyday because of its lack of response to the pedal. Not anymore!!

They make a real difference, I have one (different brand) on my 220 🙂 and never looked back.
