M276 detuned
I recently picked up a 2013 c300 with a detuned m276. The c350 has over 300hp and the c300 248.
My question is, can you just flash a c350 tune and get the same power? If so would it create any other issues?

Yes, there are a bunch of tuners that claim to giver you 300+ hp with their tune. Just search. A tune from a reputable tuner should cause no problems. The transmission and drivetrain should easily handle the increased performance.

I dont personally know, but I did come across this:

“The latest generation normally aspirated, direct injected, 3.5 liter M276 V6 engine, with a maximum of 306 HP and 370Nm (272 lb-ft) of torque, is a powerful and smooth mid range engine. This engine is available in the 2012+ C, CLS, E, and ML. Our R&D department has spent an enormous amount of time perfecting the ECU software for this engine. An increase in power of up to 330 HP and 400 Nm (296 lb-ft), as well as improved throttle response and raised speed limiter, is now available. As a unique KLEEMANN feature, we have managed to improve the software in the 300 models (which is, in fact, the same engine as the 350, but intentionally limited in power production by the factory) so the new power level becomes the same level as the 350, plus tuning gains. 300 owners will gain what is a normally unheard of improvement in power and torque from an ECU tuning.

Vaith, Carlsson, MKB and Brabus all only offer remapped ECU and V Max removal. They claim roughly 330bhp and 167mph VMax…."
