It's all the same software... I don't think you quite understand... Most of these people have the same original maps that were developed by MB to alter the tuning on their engines...
I sat and looked at the files on a laptop at a PowerChip dealer in Los Angeles... they are all broken down to engine subcategories and they just flash your ECU with preset files that have various timing maps, etc... And all were developed by the factory to rectify tuning issues with the engine...
If you're going to do a mail order tuning map, do it with a reputable company that has a physical address and a verifiable reputation... Because the only way you can really optimize your tune is by having the car on a dyno with a technician manipulating the maps as they analyze your HP / TQ and AFR curves...
