A250 re-map suggestions please

[Rs2oo]

Picking up an a250 next week. 2 owner fmsh 54,000 miles.

I live in Kent. Can anyone suggest where I can get it performance remapped ?
Does not have to be in Kent willing to travel but not as far as Birmingham ??

Does anyone know if there are any Mercedes approved re-mapping centers ? Stooopid question but you never know

Thanks

Probably the closest you can get to ‘approved’ upgrades
