The figures that he is giving you are the advance that you should be running under those load and rpm conditions. You notice that at load 30 to 70 he is recommending alot of advance, due to no turbo boost so as to keep the torque up there. AS the boost kicks in the advance figures are must less. At 0psi, or the turbo is just over coming the vacuum created by the engine the figures are still increasing as you go up the rev range. When 15psi is in the figures are must more constant, if you were to further increase the boost to say 20psi, you would need to retard the timing as the revs rise.
