If someone could decode this and let me know which version of the DME I have, I'd greatly appreciate it.
The SA said the update will cost $284 but the disclaimer is they will not be responsible if any modules break after the update is done. Also, they said it will not do anything performance wise.

Your thoughts.
You are on a very old version of software, part of version v29.1.1, this has not been updated in quite some time. Without a baseline dyno before/after the update is applied - there is no way to accurately gauge if you are gaining hp as a result.

Early builds (08-09) on older software versions (060E, 080E, 100E) would likely be the ones that see measurable benefits rather than those M3s running later flashes. Still, it's a good idea to get updated to the latest version before applying aftermarket tunes.
