Electronic throttle lock

[Nostalgic]

In theory, you could possibly achieve something close by utilizing the droop settings along with putting the engine into another operating mode when cruise is on with lower power and turbo settings to a degree. Now don't ask me how to do that, let alone do it successfully lol. I've toyed with the idea of having 2 power settings controlled with a "fault" or "condition" type derate via a switch on the dash.
