There is no single turbo solution that will offer you better performance, which is why BMW went with the borg-warner R2S twin-turbo setup on the 535d.
On the other hand, the GT2260 you have on has lots of potential, but you cannot harness it with the injectors you have on the car, you need 535d injectors to go further.
GT2260 does not require 535d injectors
Spray flow pattern is determined by the ECU , fitting bigger does not equate to a larger amount of spray
