Increasing boost on the 4x4

[Maj]

Graham sometimes those threads are spotwelded and it will break the shaft before moving, but if yours will move then you can preload the wastagate a little more for another couple of pounds pressure.

I put a switch ,bleedvalve and solenoid on my Patrol and stepped the boost up from 7 to 15 psi , had to turn up the injector pump a bit to get it fueled to suit, only trouble i had was never used low boost again....
