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.

One of the reasons I traded in my 2011 toward a 2013.

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.

I'm hoping to trade mine toward a 2013 C350 coupe. 300 horses

My ECU is on its way to Kleemann as we speak. I will let you know the outcome.

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.
