Where are they and what do they do ?
I want to put my car on the rolling road to
a) see what I've got power and torque wise, and
b) see if any changes are necessary to the fuel mixture.

I found Anders' comments quite interesting about running with a rich mixture, which when changed, gave a better response from the car.

Power run is 40 pounds
Diagnostic run is about 100 pounds more I think, but don't quote me on it

I hope the next Rigby Power Engineering day is not too far off.

Post ECU reset my car is running brilliantly again.

I await confirmation on the dyno that the perceived improvements due to Scooby Sport modifications are a reality.

Power engineering know how to look after Scooby owners, at the last meeting we had free bacon rolls and tea and coffee :-)
