Kleeman Stage 1

Does anyone out there have any experience with the Kleeman Stage 1 conversion on the W211?
This, as I understand it is the ECU and pulley, and also removes the Vmax Limiter.
If you have installed this performance upgrade I would be interested in your experiences.
I have heard a lot about Renntech, but very little about the Kleeman version.
I await responses with interest.

if you get them done at a dealer nothing.
some mbz dealers are kleemen dealers just like some are renntech dealers call kleemen.
hey I'm no expert so don't take my word for it!! just call and make sure! I've talked directly to the guy at my mbz dealer and he told me word for word that they will fix my car if it blows with the renntech upgrade thats all i know, the kleeman stuff?better call! its just what I've been told from my new buddy DR CRowder.
