Stock injectors are just that... stock. For the 617-95X the injectors are not really the bottle neck to higher performance, but they can be manipulated to give some gains. The first change is usually to change the stock nozzles from the SD241 to the SD265 found in the 60X engines. It's what is recommended by MB IIRC. They also give a bit better idle. The real only change I've found that will give a bit more HP may be the VW/Audi AAZ injectors found in the 1.9 VW diesels (canadian only versions). This is not a TDI engine, and the nozzles must be changed to MB nozzles.
PLEASE NOTE- there are mods you can do to the IP that will give much better HP gains for you efforts, and a EGT gauge is always the first step in seeking more HP.
