normally the vnt part only gives boost when u floor the accelerator, when cruising the nozzle is set for no boost so if u use a wastegate the turbo is an exhaust restriction off load and it overheats.
be better connecting it physically to accelerator via a spring and have a wastegate type diaphragm connected to the vnt also so when boost is reached it over rides accelerator spring and moves vnt to off boost.

@tpvalley Your description only controls how fast it spools up to maximum, a very poor performing option.
To control a VNT correctly requires boost to be proportional to engine load.

Make me want to get rid of my 300D non-turbo.
Keep telling myself going to get one when this one dies, but we all know these things last forever. So... ;-)
