I have an A45 Amg and they remapped it for me, their a really good bunch and Acid as he’s known has a fantastic knowledge of Mercedes cars, owns a black series c class running over 1000bhp, they’ve also serviced my A45 for the last 2 years as their a Mercedes authorised service centre.
i can’t fault them but give them a call I’m sure they’ll put your mind at rest with their knowledge and experience with Mercedes cars
