so you are only person with accurate rollers!! I don't understand how people were getting results within 5bhp of there known power, but mine is way out supposedly?
before you get all arsey

about your figure being doubted...... its well known and understood the phenomena of dyno lottery.
some dyno's read higher than realistic figures.. simple as.
250bhp from k03

is unlikely on other dynos... but the lottery applies.
I am very happy how mine reads, and the power I measure equates to the level of arflow and tune I see (and do) - they have never, ever, made that level of power level.. and stock cars also make stock power here.. My dyno is not run in inertia mode, unlike some, which seem to read higher when spikey boost accelerates the rollers, as opposed fixed rpm/sec acceleration rates
a.n.other car at the same day you went to, was +20bhp on the dyno it was mapped on only a few days earlier.. Same car will be here this sunday, so we will see the lottery numbers compare.
dont get too hooked up on the numbers.. if its going well enjoy it..
it is'nt 250bhp however on rollers such as mine.... which I know to be accurate as far as I'm concerned.
enjoy
