Turbo Timing on WOT

You would typically expect to see less timing at low rpm on a turbo setup to keep torque low and more timing at high rpm as torque begins to drop off. Likewise if engine load is lower before the turbo is making maximum boost, adding timing can help increase torque to make up for the lack of boost.
