Once I get it tuned properly I want to run about 10 psi, as the stock rb25 turbo's do not respond well to anything over 1bar for prolonged periods, or so I have been told and read on here, (there are thousands of threads on this subject).
But I was getting about 400kms out of a tank, but that was with the pfc tuned with a blocked radiator at the time, so it was tuned stupidly rich.
I have to clean the back screen at least once ever three to four days otherwise it gets blocked by that unburnt fuel soot
Hopefully in the next couple of weeks it will be tuned properly on 10psi, and I will be aiming for ~500kms out of the tank, hopefully
