electronic wastegate

There are already applications that run the wastegate without a spring. Compressed air is used on to hold the valve closed against manifold pressure. If you wanted to open the valve at low load, you could easily do it with a decent standalone, a 4-port solenoid, and a small air tank. I'd wager your gains would be miniscule at best.

The most reliable setup is and will always be a fully mechanical system. The engine management should provide bounds to the operation.

Over RPM Cutout: x rpm
Over Boost Cutout: x boost

Have a think about motoring in general until late 1990s.

Brakes = mechanical with vacuum assistance
Steering = mechanical with crank driven assistance
Throttle = mechanical
Gear selection = mechanical

What happens when you are driving a drive by wire car, with an automatic gearbox and there is a control malfunction?

Electronic Systems like this really need to be properly tested and qualified (costs $$$millions)
