i went for the full ish monty,
1.5 on the smoke screw, transforms off boost pick up.
diaphram to full adjustment, approx 180 deg, max fuel as i was upping the boost.
didn't touch the star...no need tbh.didn't want to delve too deep.
and 5-6 turns on the turbo actuator to get more, again approx 1 - 1.1 bar boost.
1500 miles in and i love it!
i always warn up and cool down my vehicles properly so i would hope the head gasket etc willl be ok.
mines an auto so gets less stress than a manual but the differnce is quite noticeable, especially on launch!
stick to the guide, do one bit at a time and keep a note of what you have done.
