tuning box worries

Hi thinking of a tuning box for my 177, does anyone know if this item can be removed for a service so that bmw don't comment on it on the service page, is the car's smoothness taken away by these tuning boxes, does the extra power make much difference to the 0-60 time? has anybody seen any figures? any help woud be great cheers
