Put my rs focus on the rollers running 99 octan fuel and bluefin and was very impressed

256 BHP @ THE FLY
221 BHP @ THE WHEELS
281 IBS/FT TORQUE

I said to the bloke who done the test for me it seems a bit high ete.. But he said his roller are spot on and are calibrated regularly they said when testing std road car there rollers where within 2-3 bhp.

The test was done @ BB Performance tuning Ive spoke to a couple of saxo drivers (friends) and they have aslo said there rollers are spot on the mark.
