Nil desperandum amigo... I have it on good authority that there has never been a reported case of a Toyota being possessed by the Devil I tried to find a graph showing boost vs throttle opening, but it seems that no-one bothers to publish how much power they make at part throttle. It is always at WOT. So I imagine that reports of boost achieved at low rpm are also measured at WOT.
To be driveable, the power output of a turbocharged vehicle must be able to be modulated by the throttle. Thus output at low and part throttle will be comparable to that of a N.A. vehicle. As I understand it, to build boost the throttle opens, more air and fuel enter the engine, there is a bigger bang and exhaust gas flow increases. This spools up the turbo so that (at a certain point) it starts creating positive pressure. This forces more air into the engine increasing the charge density which allows more fuel to be burned making an even bigger bang etc etc until the throttle is backed off.
An engine only generates sufficient output to over come the load applied, which is surprisingly little if you accelerate gently up to 30mph. So you won't get any boost if the engine can supply the required output while running in vacuum. To see boost you need to increase the load on the engine... towing a trailer full of readymix is one way, but I believe there are other ways
