How to make C350 faster?
Hi,
My car is a 2008 C350 w204.
So far, I have a x-pipe exhaust then I also removed my mufflers and replaced them with the stock resonators. Basically I just moved my resonators to the back.
It sounds so much better than when it was stock and I'm really happy with it.
However, after doing that to my exhaust, I didn't notice any increase in power
Now, I'm wondering what other modifications can I do to make my car go faster?
A Mercedes technician suggested that I change my mass air flow sensor (MAF) to an AMG MAF sensor, he says that it will increase around 50hp.
Is that true?
Any other suggestions for more power?
Thanks

Bottom line, if you want a serious hp increase, you're going to need some sort of FI, and from what I understand, it is a huge undertaking and a huge expense to go turbo on these cars. You would be better off selling and getting a C63. These cars weren't meant to be fast. I have researched how, as I am very unsatisfied coming into my C350 from an E46 M3, and I've come to realize this car will always leave something to be desired, and will never be what I want it to be

Another round of ICE
How much faster is necessary? Power:weight ratio is the key. For some increase in daily driving, reduce weight. Leave the spare, jack, and anything else in the trunk at home. Keep the car between 1/4 and 1/2 fueled. No passengers. These will offer a small improvement. If you think a C350 is a full category off your need for speed, you need a different car.

Any other suggestions for increased top speed/acceleration?
How about an ecu tune? which brand is best?
(Renntech, Eurocharged etc...)
Are there any plug and play ECU tunes out there?

You can put intake manifold/82mm TB/ injectors from 09-11 SLK350, after that do an ECU tune from E/C or RENNtech,,
definitely, great results will gain after tune it..

2010 C350 sport
I would contact Cory at kleeman about an ECU tune. I had it narrowed down between renntech and kleeman and I think kleeman has better and more competitive products/prices. Their K2 (stage 2) Package is around $3000 and I am really considering this as it is conservatively a 30 HP gain with a much improved throttle response. They also have the K3 package for around $8000 but this is more than I want to spend at the moment. Just my opinion

Wow ecu tune is quite expensive though,
How about a Nitrous express kit?
Its cheaper right? but would that be any good?

You can get a tune, which will add maybe 10-15 rwhp. The MAF will not change the power, if at all, that your car makes. There is little to win power wise on these cars. I do tune them so overall there are benefits, just not many. You are better off with a C63, where a tune and exhaust brings larger gains (and sounds).

As silly as it may sound, "Sportstick" has already given you the most realistic approach. You're next logical step is an ECU tune, then possibly lighter wheels, however each step will require more and more $$$.
It is unfortunate you were not aware that an X-pipe yields no power gains and actually devalues the overall worth of the vehicle.
