Ask S&S Motorsport, they did ISX XPI injectors some time ago, they are same as Scanias.
Celect M11 had problems with shifter, and it used stock nozzles..

Yes you can go larger than 30% with Extrude Hone, but it makes for a dirty, smokey mess. Even extrude honing only 30% will net you the same dirty, smokey mess.
Micro EDM, and a very minimal bump hone will yield the best results by far.
