According to that video, the Piston and Tappet plate have also been upgraded. The piston is now re-enforced and has a half-metal rack and the tappet plate's been upgraded somehow as well. Incidentally, the mosfet is a basic stock version and is not programmable.
According to "Dizzy" form the Overhoppers Blog, they're obviously shipping now in some places as his new M27 had the upgrades. Here's his review:
