All electric actuators or motors die over time due to heat and moisture. And the valve usually leaks or gets blown out in hard acceleration on boosted application. Lastly the decreased back-pressure has significant enough impact that another tune is needed on my other car, so every time I go WOT, the cutouts have to be open if that is the map is used.

In the end, I would not go electric cut-outs again. Maybe manual cut out with a block plate for a true track car.
