Interesting stuff from Turbosmart. EFR focused actuator. Flexible rod and better sealing, sounds like? The position sensor is interesting, but not something I would be able or need to make use of.

Speaks about it here for a bit, along with the electronic wastegate stuff, which is pretty neat sounding -

I suppose as I'm still on a single port actuator, seems like a good opportunity to pick one up in Jan' 2020 release and go for a retune. Currently on a 14psi spring, and peak at 24psi, and tapers quickly. "Ran out of wastegate", per my tuner, definitely leaving power on the table.

@YamahaSHO, what spring pressure are you running on your twin port setup? Are you using the MAC 4port solenoid to control it? Did you settle on a preload setting?
