Well there are a few things you can do i am not that sure about the MB aftermarket I am just now getting into it. But i am sure you can Chip the car, add a figher flow intake(gain hp but loose tq.) aftermarket headers, and the MB exhaust seams to be well engenered but you could awalys use a diffrent exhaust. With the C240 with any of these mods you could loose low end tq. but you gain high end hp. You could also add a supercharger but that would be more hp than you are after.

You know what i forgot almost completely about Renntech they make plenty of parts for MB's go to there web site they have plenty of mods avaiable. There exhaust claims to add up to 35hp (hard to belive unless you have one of the big 12cyl.) They also make tuning kits and intake and aerodynmic parts.
I have personnaly added a Upsolute chip and a remus exhaust and have felt no <significant> changes unfortunately. the 240 engine is pretty maxed out as it is. Only renntech kleeman and amg kompressors will make a difference you can feel. the best bet is to swap for a 320 manual and then chip it...
RENNtech is the way to go! I'm biased since I am a dealer, but you can get an ECU upgrade for about $1600 for 10 extra HP. That plus a carbon fiber airbox gets you 15 bhp for $2495. Or those two plus a sport muffler gets you 20 bhp for $3350.
I can help you out with any of these. Post here and let me know how to contact you if interested.

however, why would i pay $2500 to get 15 hp from your adjustments when i can get 13 hp from the evosport pulley for $500? i am not very familiar with either type of modification, so please inform me why i should buy yours.
I can't speak for the evosport pulleys because I know nothing about them, but the money you spend for RENNtech parts gets you the R&D of AMG's former North American technical director, Hartmut Feyhl, the founder and owner of RENNtech.
While an underdrive pulley might free up some horsepower, a RENNtech package is a thoroughly engineered system to upgrade the performance of your MB.
The ECU upgrade, for example, takes the actual ECU from your car and re-maps the 3D engine mapping, whereas most "chips" just add extra fuel to free up some HP.
Granted, RENNtech parts aren't the cheapest aftermarket parts around, but then MB's aren't the cheapest car on the road. The HP and torque gains you get will be reliable, come with a warranty, will be more "useable" power throughout the rev range and won't interfere with the rest of your car's engine or body computers.
Like I said, I'm a bit biased, but I truly believe in the quality of the parts and the integrity of the engineering.

Forget any changes to the 240 engine.
Its main weakness is low-end torque - and whatever you do in the low-dollar bracket (chips, etc.) will make that worse. You'll gain a little vmax (which you don't need - the car is much faster than you can drive anywhere in NA), but loose acceleration, especially at low revs. And your MB warranty will be gone, too.
The one thing that improves low-end performance a little is hi-octane fuel (98 or 99) but, as far as I know, that's not available in NA. (But take heart - the difference in performance is not worth the difference in cost over time.)
Hi-dollar mods (compressor) may work, but then a total mod (i.e. a change of car) is probably cheaper and more effective.

Underdrive pulleys turn the alternator, a/c compressor, power steering pump etc at lower speeds, thereby consuming less of the power produced by the engine and freeing it up the drive the wheels. These pulleys are also usually lighter than the stock pulleys, so consume less power themselves.

I would also recomend you getting the Evosport pulley. I had it on for almost 3 weeks and I have NO complaints. It is a significant gain and it isn't to expensive. As long as your there make sure you get the C32 brake upgrade. If you want a bigger boost in HP, well then buddy you got the wrong car... unless you got 8-10K to spare for the Kleeman supercharger. But only ballers like BrabusCClass can get this!
I went with a stainless/polished Magnaflow axle-back (#15615) for $140 and replaced my stock cats with Magnaflow metallic-spun high flow cats (#59959). The tubing is already stainless and mandrel bent, so no need to change that. My total cost for the exhaust installed was at $500. Way better flow and sound.
As far as the intake, they're already optimized for maximum flow from the factory, so I just change out the plastic inlet tubes for a couple of smooth polished tubes with cone high-flow are filters (I removed the stock panel filters of course). Hope this helps!
