Hello All.. I am a fairly new owner of the 2014 C300 Sport 4Matic. Have been reading a lot about M272 engines and M276 engines on C300s between 2008-2014

Can someone please tell me which cars have the M276 engines.. ( I believe mine is a M276 engine but someone please correct me if I am wrong )

Have been following some threads where many have mentioned that the Mercedes detuned the 2014 c300 M276 engine to 248 Hp and the same engine is used in C350 to give 302 hp.

So does ECU programming from Kleemann or Renntech or Eurocharged give the M276 engine on C300 its full potential of 300+ Hp.

Thanks in advance.

2014 C300s are the new M276 engines.

Kleemann claims to get the C300 to 315ish hp, but they have no dyno sheets to prove it.
