Trust me, it doesn't work like that.

I work for a company that develops diesel fuel injection systems.

Ok fair enough,  i dont claim to know much about diesels at all. 

But, with that being the case,  would fitting a massive intercooler be a waste of time?  Or is that more to do with reducing hot air to warm air but still not cold?   I was thinking about a fmic for my tdi.

with diesel dont want things to cold but like wise not to hot,   getting the boost up seems to give more efficency and power.   loads more fuel =  more torqe lots of smoke  and dosent do the engine to much good.

I ran 2bar of boost on my TDI and it never smoked, pulled hard and smooth and fuel was no diffrent to stock really,  but i wouldnt like to boost any harder than that.   Upping the boost is something i would leave out untill the whole engine is ready for some serious power

To a diesel warm air is the key, that's why loads of effort is placed on getting cold starting equipment running right on the injection system.

It's more to do with ensuring the compression stroke of the engine has enough help from the warm air in the cylinder, as it keeps the lining warm and aids combustion as warm air has more power to it than cold air (that's why boilers use warm air)

Either way a cold air feed will not help as with cold dense air comes moisture, and with moisture comes half assed combustion.
