No not yet, probably going to wait for winter around here, but I lucked out and found this one for sale and jumped on it. I have heard that the throttle response is greatly improved as well. If I get a bug up the ass and install it I will let you know.
I had to buy all mine new but I like the better throttle response and i have not had any problems since i installed last year. I am happy with it. Good luck and have fun mounting the coils unless u get the fuelrail covers.
