I have the Kenne Bell system on our's for the past 30K miles. We used a group up in mckinney i can find the digits for you. They started out on suburbans at Reliable and ended up doing airplanes and Subaru WRX's in full race mode.
We couldn't be happier with ours. Once you get it all buttoned up we should do some comparisons.
