Set the rod to just sit on the stop screw and wound out the dawes, about the thickness of the lock nut. Test drive gave me nice linear boost up to 16psi while accelerating up to 100kmh. Took up the same stretch of road and am now getting 14-15 psi at 100kmh with cruise on, up from 11psi.
Boost is peaking at around 16-17 psi which is where it should be if I understand correctly.
EGTs are under control, high 200s low 300s.
Going to keep an eye on it and chase up some springs to keep in the spare parts bag.
Thanks everyone for the help.
