More Info on KLEEMANN K23 Tunning Kit Needed
you have exhaust as well? That would sound like a euro beast. completely badass!

Do the instructions mention anything about zeroing out the car, or I guess that is being done because you sent the ECU to Kleeman. I actually called Kleeman to see about having this done on my C230K M111. Said, nope we don't do those for that engine.

The K&N installed.

The connections in line for the K-box, it connects to the mass air flow (MAF) and the manifold air pressure (MAP). Like I said they made a mistake and no programming is required for M271 engine. The K-box goes in the fuse box under the hood.

Header install, the bends could be better. It was a little off, so it went in tight. I tried twisting the header and the cat every which way to make it fit better, and the stock bracket. so we will see how it holds up.

The pulley's installed, the water pump is smaller and the main one on the crank is larger. the belt looked a hair longer??? It was hard to break the torque on the crank but a good impact should work. then it takes a heck of alot of torque.

The fuel pressure regulator, it is mounted back by the tank in line with the return on the fuel filter. It uses a vacume line that you have to install from off the manifold and route back to the regulator. there is a open hole in all the brackets with the fuel and brake line so it looks like it belongs.

I think that covers it all, I did forget a picture of the oversized cat. It is much larger screen on the inside for better flow so I think it helps. I don't have time this week for the dyno but I will try next week so I can post results.

Since you are a worthy pioneer
and have had all the kleeman kit installed would you mind answering some questions about it???1) Has the cold start of the car suffered in any way?
2) Does the car rev cleanly in all the rev band without hesitations sputering etc??
3)Have you ever had indications of pre-knocking ?
4)Have you had any indication that the stock chargecooler of the car is not enough after you completed the conversion to kleeman??
5)Can you give us your general impressions about driveability, the quality of the tuning kit and whatever else you may find useful for prospective buyers of the kit??
As far as the k-box is conerned,when I inquired about my slk,which has a similar if not same version of the m271 engine, I was told it was necessary. I suppose the ecu of the slk needs to be tricked somewhat .....
Congratulations for a great c-class
You just bent over and took it royally up the wazoo man..
what a stupid decision.

I think you now the saying about opinions,there just like @%#$* everyone one has one.
I think opinions are great without them these message boards would be so lame.
