I have no other mods. I just bought the car on Sunday with 60k miles. It's in great shape. I chose the KKM due to good reviews over it and the guy at spmotorsports told me it was a good choice. I just thought the superchip is the next best thing. I am a former ricer so I'm just getting into the swing of things with these cars, but I do love the car. Much better than my civic I have.
