"The software status in the vehicle is:
I-stage, plant: E89X-08-09-530
I-stage, dealership network: E89X-09-12-512"
Does this sound about right? Update or no update necessary/recommended?

Recommended. You have very old SW as well.

Here are 2 seperate instances in which the 231E flash has showed considerable gains. Tests were performed on 2008 M3s, one 6MT and the other DCT-equipped.
MY08 6MT, 080E vs 231E
This particular M3 failed smog, even after plugs were replaced. DME was Identified as 080E, indicating very old SW. Updating to 231E provided an 18hp gain in power, cured his misfiring issue and was able to pass emissions.
MY08 DCT, 100E vs 231E
This was the car that started it all. This 2008 DCT with 100E ran a very low baseline. While his car was in for the VF620 supercharger - we wanted to perform a before/after test on SW versions to prove this wasn't only a theory before the supercharger was installed. As a result - all DMEs are now updated to the latest versions before tuning/supercharger installation.
After updating, a 20hp gain in power was achieved - looking much better than its baseline run. We're clearly on the right track.
These types of gains aren't seen by clearing adaptations on NA vehicles.
