Kleeman ECU tune, 3.5L C300
#28
I received my ECU back today and let me say WOW!!!!!!! I have had upgrades on other vehicles before but this one is really worth it. If you have a 2013 C300 this is a must do.
Timed the car 0-60 4 times:
1. 0-60 5.7
2. 0-60 5.9
3. 0-60 5.6
4. 0-60 5.7
And the response in the accelerator is immediate.
Well money spent. Call Cory @ Kleemans.......

That's great to hear, those are some pretty quick 0-60 times too. I'm hoping to hear many more good reviews like yours! I'm wondering... my car currently can't rev to redline in park, with the tune can you rev all the way up to 7k?

P.S. End result is typically about 315-320 HP and about 300 lb/ft. of torque.

See here:

They claim the C250 tune on the M271 EVO results in 245 HP / 276 lb.-ft of torque.
Quite a bit more costly then the JB+ tune, but nets in more power/torque as well.

I just shipped mine out today, hopefully will have it back before the week ends.

Yup, but the MB tech would need to be a computer engineer to tell the difference. I'm willing to bet ECU software is written at a very low level, you would need to be an absolute expert to tell the difference between modified and non-modified ECU software.

Tons of companies have tunes for the M272, search around. They only seem to offer maybe a 5-10% increase in HP/TQ. 4matic generally doesn't matter.

The reason the power increase is so dramatic is because the engine in the 2013 C300s are just detuned C350 engines. The M272 tunes (MY '11 and below) are typically much cheaper, and can be tuned and un-tuned via a handheld tuner.

Your profile says 2011, but as far as I know Kleemann is the only company that offers it. The OP said he contacted many company's that have 10-15 horsepower tunes for ~$600. But Kleemann is the only company with the full retune, for whatever reason.

2013 + models have the 3.5 motor, Mercedes detuned them to 248 HP. The C350 (which has the same motor as the 2013+ C300) has 302 HP. Kleeman is simply tuning the engine to its capabilities + 20 or so HP.
I have done this tune and speak from experience. Best tune i had ever experienced.
Again, no offense to your local tuner but i would not trust anyone touching my car except Kleeman.
Money well spent...
