The oil has to be going somewhere. It could be leaking past the injector Orings and burning at a very light rate. Did you sample the whole depth of the fuel tank?
If you're getting injectors, you could get some better ones, from a higher hp rating
The Cat number for the good ones is: 10R0781 for a reman, but that's if it has the higher volume HPOP.
If you get the good injectors and the bigger HPOP, you'll be pushing 400hp. Of course, that would need a bigger turbo to keep it cool.
The other idea(and much cheaper), send in your injectors to get rebuilt, and have the nozzles honed out for a smaller hp gain(stock, up to 350hp).
