look up any word, like hipster:
 
1.
When a company, product or brand is enhanced/ tuned to a particular market or segment.

It leverages existing marketing, PR and brand assets, and is not a re-launch or re-branding.

This especially comes into play when a brand is tarnished by bad service, PR, ill-conceived advertising and needs to be counteracted by tuning.
The new commercial for XYZCars requires Brand Tuning - the image with the car speeding through the suburbs with young passengers promotes irresponsible driving.
