Assalm-0-Alaqum,
I am also hearing the samething end of this year. Well see who wil do it first, will it be some garage or performance shop like maxpower, R speed or BHP.
Well if you are check the some model bhp you can check the spec. on the internet, but checking your own car that is on dyno and one other thing there ther is come electroic device that hooks on the battery or something but it tells KWatts and then convert it in to BHPs
