was only joking mate
Thought I would get a couple of bites with that one
I totally agree, its a dyno lottery anyway. At least you get an idea if your car is running properly etc. My last car was dynod on DD rollers, and found that it wasnt running right, and I sorted the problem, so it was a good fault finding tool.
The good old saying that they are designed more for setting up and live mapping cars, than they are for a precise measuring tool can also be said.
Just like the motorscope day when the rs focus bloke found out he paid £2500 for a mountune tuning package, that actually produced 20 bhp less than a standard RS focus with a panel filter on the same day etc etc
