Are these tunes exactly the same tune as that used by BMW, or are these simply each tuner's effort to create a map that's as close to the BMW version as possible? I've researched but can't find a clear answer. It seems like these are more like an approximation rather than actual CS tunes, correct?

OE = Original Equipment
OEM = Original Equipment Manufacture
For example,
ATE, BBS, Brembo,Textar, etc.are OEMs. Textar brake pads made to BMW specification without BMW labeling or packaging is OEM. If the same pad is made by Textar for BMW, have a BMW part number, packaging, etc. then they are OE parts not OEM.
Like to generic drugs they are very similar but not the same.
