Some info on the electric wastegate actuators:

"Electric actuators provide higher control dynamics and better accuracy and resolution in controlling the position of the wastegate,
since they are independent of unstable vacuum conditions found in gasoline engines,"
"The improved performance allows more precise control of the turbo charger in critical areas of operation
– a major pre-requisite for increasing the lifetime of the charger.

"Electric actuators also shorten the so-called 'turbo lag' and produces less 'turbo flutter,'
a sound heard when lifting off the throttle in a turbo-charged car.
Some have described this noise as the sound of a chipmunk or a rattlesnake."
I wonder whether the electric control over the wastegate will be an advantage for tuners, or just one more "problem" to overcome?
