The wastegate is working - the bug already reported is that the displayed
value in the property tree is taken before the wastegate code is applied.
This is quite useful when developing, because it is possible to check that
the supercharger output is reasonable. Anyway, my earlier diff retained that
while adding boost readouts post wastegate.
