The setup of the rolling road seems to effect the results a hell of a lot as they could get figures for mine ranging from 280BHP to 250BHP.Mine was run by Chris who use to work @ PE doing the work.He's a knowlegable guy on RS's so u can imagine what an Optimistic RR operate could tell u !!!
Does seem strange, I took mine for a RR de-tune, took off a faulty chip, they said it was the first Cossie they ever de-tuned!
