In this case it'd only be 5 though right?

Besides, 4 of them would be linked together anyways...You might not even need to vary their position against load, just engine speed.
WoW, 15% seems a little sketch but if it's just the throttle, that could be possible. I am not informed on this by any means but it sounds to me like considering the flow of the entire system rather than just one piece would make that difference look much smaller. With TGVs sitting in a narrow part of the intake tract though, yea I imagine smoothing out the valves and stuff would help. Just throwing ideas out there, but maybe sanding the pivot part a little, and then using some epoxy or foam or something to slightly fill in the small gap, maybe rounding off the edges too (although that could mess up very low load behavior).
