Calling all long time JB4 owners

[Lehn]

Howdy

Just want to hear all you JB4 owners what you think about this little piece of happiness after living with it for some time? Any errors, faults, broken down pieces? Or just huge smiles?

I'm asking out of curiosity since all seems very happy with their JB4 after the first few hundred miles but what about after several thousand miles?

Thank you

Been a few friends like this now, but following nevertheless

I've had a JB1 and then JB4 for 15,000 miles easily. Very happy and can't fault them at all

Very well regarded in the US and a very long history particularly on BMW tuning, they would be my black box of choice if my car wasn't manual (but even then always been tempted by map6 to adjust torque levels )
