Driving a 2013 C300 loaner few a few days. Absolutely blows the doors off my 2012. Makes me realize what a slug my car is.

The thing with the 2013 C300 is that it's operating at 70-80 horsepower under its capabilities. I would say even when you go WOT you are only getting ~70% actual throttle opening. I'm getting my car tuned in the spring when the snow clears.

Have you confirmed that, suggesting they used the same MAF sensor and limited the output voltage? I thought they would have been more aggressive in de-tuning the engine.

2013 C300 has become a recent addition to my garage. I would be interested to find out about the outcome of the ECU re-work. When do you anticipate it coming back MrMeth90?

I link this thread pretty often, but it's got some pretty vital information on the M276 in the 2013 C300.
