Hey there,

I came from a fbo N54 with a JB4 g5.

I loved it and I usually ran map 5 (auto tune). Long story short the cars sold and I have the C400 now.

Is there an auto tune map for this platform? I just installed bms dci, is the JB4 learning the difference of the dci? I installed amg 450 mufflers and did a rear resonator delete, does it learn about this flow and less restrictive exhaust?

Now Iím thinking about buying dpís but am thinking do I need an ecu tune for all of this? I feel like on my n54 it was all plug and play in terms of upgrades and the jb4 learning, can the same be said here?
