So....now I am waiting for my dawes valve to arrive so I can control the boost and limit it to 15/16 psi.
from what ive read the majority are adjusting turbo so if it happens to me ill probably look at that or chase up some parts and do the double dawes as i like the boost curve on the diagrams put up by chaz hope im right by saying chaz i do have the diagrams saved for this setup
