[brainpool]

hello guys,

i have an E39 2003 525i M54B25 MS43 and want get a few HP more. Im reading about OBD II Tuning on some websites which costs about 300 ?.

I have an ADS Interface, which ist working with INPA, NCS Expert, etc. Ist it possible, that i optimze the DME on myself?

Which Software do i need, Progman?
Where i can get the tuning files for the DME?

Tuning is work for professionals who have a lot tools - like a rolling road and gas analyzer.
If you change the wrong part or make a change to the right part that is incorrect, you may end up with less horse power or even a damaged engine after some time.

yes thats right... But i thought, maybe there are some tuned dme config files, which i can use.
