Powerbox was on the car for 15k miles and I loved every second of it. My car was a 6 speed manual and the improved throttle response definitely made driving the car a lot easier and definitely a lot more enjoyable.
Downside is that one of the pins was broken during the uninstall. However this can be easily fixed by terry over at bms, all it needs is to be soldered back together.
Price is $150 firm picked up.
