Search online for "Mercedes coding." Several companies will appear, from various parts of the world. Not all of them offer the VMAX option, so you'll have to do some research. I know of one company that does offer it. It's RJ Automotive, located in the U.K. Link: RJ Automotive Please note: I've never used RJ Automotive and I have no affiliation with them.

MB’s of all kinds.
Usually a ECU tune will remove the limiter as well. Kill 2 birds with one stone?
