Audi 3.0L engine, difference between them?

Does anyone know the difference between a 3.0 218 PS (215 bhp - 160 kW) and the 272 PS (268 bhp - 200 kW) engines?

I read elsewhere the turbos are the same, but recall when I looked into it for an earlier 1.9tdi they used different injectors, making it uneconomical to upgrade. Is it the same on these engines, or is it really just a different ECU map? Obviously the bi-turbo has another turbo, so that's kinda obvious.

I find the easiest way to check is to look on a website like superchips and see what it remaps to. If it’s the same as the higher powered engine chances are they are the same just detuned. Looking at the 3.0 tdi the 218 bhp version only remaps to around 270bhp but the 272 will remap to around 330ish so there must be some differences.
