My one isnt runing yet, but i tuned another rb30/25NEO that i built, with an rb26 ecu and nistune. Its probably about as complicated a setup as you would want, using a custom afm, but it tuned up fine.
That does sound more likely, as im sure the autronic cant be that bad relative to the vipec. I mean the only bit that would really effect the drivability would be the cams and to some degree the tps mapping although i think thats pretty much sorted as autronic have been doing it for years.
Why would you raise the fuel pressure when the fuelling issue is already fixed with the injectors. An 040 is more than adequate for the power he is making. Wolf is map sensored.
Im assuming the injectors were limiting the power, why it is running 1.1 bar to max out the injectors is the real question.
You need to remember that setting up the cam gears is a bit of a time consuming process in an rb, as the cas need to be removed every time you want to adjust, so it will cost you a bit in dyno time.
It works fine, however if you run significant boost, then the housing will split/crack. The only real reason i can see for doing it is so you can run an amo BOV without the overfuelling, but for that to work the afm has to be plumbed after the BOV
