Who's quoting those figures and is it a tuning box or an ECU re-map.
On a note of caution, I read elsewhere that on the first occasion the car goes into the dealer, BMW will know you've installed an unauthorised modification and your warranty will be compromised.
Don't know how much truth there is in that, but it makes sense from BMW's point of view.
