What would make the car judder or vibrate oddly from the rear on the dyno ???
It was doing it at about 4/5000rpm when on its power run come to think about it now

Could be a few things, not strapped down properly or the rollers not working properly or wheel spin (on the dyno i use it sometimes wheel spins in 4th).

We adjusted the strapping 3 times from tied down to proper loose.
I had new DS2500 pads fitted on my service the day before, when fitting these the guys would have clocked a seized caliper no ??

New pads, juddering from the back, low on dyno power...
I'd be getting the back jacked up and checking how free the wheels are.
You will also feel the wheel to be unusually hot after a bit of a drive.
But either way, losing that much power would feel like driving with the brakes on!
Did Romain offer any suggestion?

Romain was busy with customers when I turned up so after spending over an hour with me he had to crack on like, I'm going back down there soon though when we can have a proper go at it.
I've been having battery issues of late so Im going to change that, get new plugs and give teh filter another clean then start from there.
I just thought I throw it up in here and see what you guys thought .

A mates 350Z lost a similar amount of power betweens dyno runs, we found that oil from the K&N was fouling a sensor-air flow or the like- back to standard and the ponies came back to the corral, could it be anything like this? clutching at straws sorry.
