When I had the new TD05 turbo fitted with the new lump last year the mechanic (in very loose terms) said he had the boost turned down by adjusting the actuator (top of turbo) on the arm?? As I'm running a low 0.65 bar of boost []can I adjust slightly by adjusting arm?? If I do it bit by bit then checking by driving , this should be ok should'nt it?? Cheers.
