Can someone explain this to me? Did Mercedes intentionally de-tune the crap out of this engine from the factory?
Where does the extra power come from in the tune?

Is the m113 engine in the C55 really that much worse than the 6.3? K&N filters, no second cat, and a tune will net you approx 400bhp...correct me if I am wrong. Same mods on a 6.3 you will get around 530bhp.
The new engine makes roughly 10 more hp per liter.
I was able to find a write-up and I guess they are a lot different... I did not know that. 3 valves per cylinder to 4, SOHC to DOHC, increased rpm, twin throttle bodies...
Ok it all makes sense now.

I understand that the C63 WOT tuning leaves the throttle body butterfly at only 50% compared to the same motor in the bigger cars. Aftermarket tunes solve that fairly easily apparently.

I thought there were some minor mechanical differences also. Doesn't the E63 have slightly higher compression than the C63 also?
Yes, there is no point spending millions on R&D for a new engine when you can detune your current performance one from the parts bin and use that. So yeah they made it crappier to differentiate the C class from the E and S, in my opinion of course. The ecu tune on the C63 and E63 come out about the same afterwards. The C gains 50hp, the E gains 10hp.

As mentioned, the C63 throttel doesn´t open full at "wot", it´s limited by
the ECU. Another thing is that the headers are smaller on the C63 to fit
in that small enginebay.

The m113 was first released in 98! Its amazing the m113 has stuck around till 06 when the m156 started showing up. Its just a HUGE different in technology that makes the new motor an absolute beast and makes m113s look dated.

I think it has more to do with the C55 MAF (not on the 63) than the tune itself. The C55 is NOT a very tunable car with the MAF. We are going to get rid of the MAF on my Kleemann so a "real tune" can be done.

Not all cars are created equal. Check this out between my OE-tuned C63 vs a Eurocharged tune C63..

Well if this is true, this just about seals my next car choice. I was toying with the idea of trading the C55 for a P-Car or going Audi S-line, but you cannot argue with effin 530 hp in a 4 door everyday runabout. That's what I LOVE about the C55, such an easy and pleasant car to drive around every day to do errands and a real beast when you step on it. The C63 should be even better! 530 HP, ****!

Its near impossible, as many have learned, to tune a NA C55 with the limitations of the MAF. Using a new ECM makes all the difference in the world for tuning and this will be my winter project with the boys at Speedriven in Palatine.

Yeah man, I hear that. I'm just itching to grab a C63, just want the prices to drop some more ad I'm too cheap (and with too much other debt and priorities!) to buy one now. And it's supposed to get even 'stupider', the next generation C63 is supposed to be using a derivative of the twin turbo V8. Exhaust + tune = rear tires turned into smoke very easily...

and being FI, much easier to "tune."
