No..... the map that MSL will send you will be absolutely fine to run without any further tweaking.
I plan on fitting some aftermarket down pipes and some K&N/Piper Cross filters, so once I have these fitted I’ll take the car to MSL for some final tweaking as the map I ordered was the Stage 1 (totally standard car, with no additional modifications). As part of you ordering the map from MSL, they will ask you if your car has any other modifications and if you have.......the map will be tailored to take these into account. MSL are the Mercedes experts and have done so many cars, they know where changes will be needed to take most modifications into account, or you can pay them a visit and they’ll put you car on their Rolling Road which simulates real driving and they will check items like the fuelling (Air to fuel ratio), Timing and Advance Curves, Boost Settings etc to ensure all parameters are correct and optimised.
If you have no other modifications, you’ll be totally fine with the map they send.
“Acid” and his guys are all very knowledgable and will answer any questions you might have and also advise you what options you could consider for the future, should you want even more power........ It’s very Addictive
