you guys,
Im going for
Evosport underdrive pulleys/ green filters for first!
Then, Hopefully I will get the Renntech Headers for the SLK55 because Kleemann wont sell me parts they must install it for me in a specific dealer which is another Country

I was just thinking about parts that are most effective for Keeping the SLK non supercharged and the best way is for me to do
get
1) Headers
2) Green filters
also I contacted Speedtuning they told me their Ecu gets the SLK to 393hp and costs $399 dollars How about that !

You might also consider switching from shim over-bucket valve shims to either a shim under-bucket design or a shimless design. The shim allows for the valve adjustment and there are different methods by which this is acheived. For high rev applications, shimless is the safest followed by shim under-bucket and then shim over-bucket.
Just my humble opinion (backed up by experience and some pretty serious research).

It is the best route if you aren't going to supercharge the engine. This increase will normally dwarf other bolt-on modifications. Stay away from reground cams (stock camshafts that are upgraded by having material welded on to the cam lobe and then ground down to new specifications). Think about also inversting in new retainers (part that holds the valve spring in place) as well as head studs (the holts that hold the head on the block) to cope with additional cylindar pressure and minimize the risk of a floating valve.
You might also consider switching from shim over-bucket valve shims to either a shim under-bucket design or a shimless design. The shim allows for the valve adjustment ans there are different methods by which this is acheived. For high rev applications, shimless is the safeest followed by shim under-bucket adn then shim over-bucket.

Thank you for your Humble Response!
For now, I am getting Headers, and Green filters
Later on I will treat my self to Carbon Airbox !

For anyone who is just getting started in the modding world, check out this book. It is REALLY great for beginners. I think that it would be too simple and mundane for advanced modders. But for us beginners, it is quite an interesting read:
http://www.amazon.com/gp/product/076...Fencoding=UTF8
It is called "Car Hacks & Mods for Dummies" by David Vespremi. I find the book very informational and fun to read.
Check it out.

Does it make the car run more effieciently like for example in driving response

waiting for the green filters to be instock, and thats all for now!
I thought about the headers they are just too exspensive!
In the future an Ecu would be nice!

I think they're telling you bull****... I would make sure to get a Dyno run just in case you get ripped off. Just friendly advice.
The same for the pulleys. As was mentioned already, the pulleys most likely will not up power at all, or if they do, only 1 or 2 ponies. But I'll reserve judgement until someone produces some dyno graphs to back up the claims

I have been wondering the same. Why some other ECU tunning company can squeeze like 30 hp and tq from NA engine. While many reputation ones like Brabus, Kleemann etc cant?
Are they being conservative about the figures or these other companies just over stated their figures?? May be Kleemann do not want to squeeze too much off it because of some draw back??
Have alwayysss beeen wondering...

I know underdrive pulleys for a Mustang add about 10-12hp, but there is a draw back. By underdriving the accessories you can have charging problems at idle because they are spinning so slow...specially under a full load...aka a/c on, stereo on, etc. and you can have cooling problems at idle too since it slows down the water pump also. This is one reason why you can't run underdrive pulleys with a supercharger.

I to think that is a crock of crap. over 30hp only on a fuel curve remapping, yeah I could believe it if the car was supercharged and you had a custom fuel curve remapped vs. running a stock one with a SC or turbo. I know Speedtuning states you can't run anything less than high octane after you do it...need 91 or 93 depending on the chip you have installed. Where as with the stock setup you can run 87 if you want, but will have less power because the computer will just retard the timing to deal with the lower octane rating to stop pre-detonation.

mmm, I thought they did. But anyway... there's several companies that do offer it. I still would get the headers as a first step.

Why are you such a tight a$$. You buy a good car and you want to master it with cheap junk mods. Just dont get upset when your 10 mods which each add 5 HP dont give you 50HP.
The problem is that when you do one mod it moves the posts around and the mod following needs to fit / complement / contribute to the effects of the first mod. So adding / throwing / cheap a$$ modding doesnt mean you are adding more and more power.
I wouldnt be surprised if you didnt get a drop in power around 4000rpm according to the compounding of competing inputs and then a small increase at higher revs. There is no such thing as a linear increase.

How anyone can detect 10hp gain over 400hp engines is a complete mystery. It would mean they have sensory sensitivity of 2.5% or something like 0.025 G force for every 1.0G force of acceleration which is not much at all. But if you hand over reams of cash then it must be obvious that the results are there.
