'glacial pace' - that's funny and really true.

I'm not even sure if a re-ground cam would even work in the valvetronic mechanism. The problem is the re-ground cam leaves the peak of the lobe where it is and makes the base circle smaller. The geometry of the valvetronics doesn't look like it would compensate and make more lift. Watch BPC video on the N52 head especially around 3:45 onward. Even a different cam with a higher peak would push the intermediate and rocker off their ends. It's a very delicate/precise dance the whole valvetronics mechanism performs.

The stepper motor- 1 revolution is about 7* and from min stop to max stop is 25 revolutions, 25.25 if I force it. That is 175* to 176.75* which is right where I measure. I could grind the max stop to get to 180*.
