The way this setup works is someone purchases the OBD2 flashing kit from VF and then they are able to download tunes from their computer and flash their car themselves. A very trick setup indeed that eliminates one needing to send in their ECU although this will not be quite as aggressive as a custom dyno tune. Oh, and this will also work for supercharged cars and other modifications can be tuned for as well remotely.
On to the results. The baseline for the car (we do not know if it is manual or 6-speed and feel is quite low for a dynojet) is 324 wheel horsepower with the 231E software on 91 octane. After the tune, peak horsepower rises to 338 wheel horsepower for a gain of 14 at the wheels, solid.
What we see here is the 231E software did not provide a very strong baseline. Furthermore, aftermarket software will still easily outperform it even if it is a canned tune let alone a custom dyno tune. The 231E hype seems to be exactly that, just hype. Results and video below.
