Good work Jez. I noticed fitting a kit to my old MY03 Zed that it did make a noticable difference when pulling away and idling, but no real difference other than that.
We did notice a few years back that some cars had good grounding and some were pants. Its pot luck what you get. Some see no difference from grounding kits and some see good differences. You just dont know til you fit one Nice to see some science applied to it though, when I got mine it was a case of just listening to the car and seeing what happened on the butt dyno. Good to see it proved that when it does work, it makes a measurable difference.
