Many thanks for all the input. It looks like a real 50:50 split with some saying dont bother as i wont be going to the track which i can understand. Then others saying do both and enjoy the experience. Can anyone confirm that the remap makes the car louder? I think as money isnt a worry, i will go for both options, ideally together, but if thats not viable then remote remap so i dont have to worry about the dealerships reflashing the ECU during a service / warrantee issues as i plan to continue the mb service history and LSD if i find that i cant make the most of the power increase. Kind regards. James.
