I am trying to spool my turbos while foot braking and it seems like the pcm is pulling timing on its own. i have the base spark in gear and high octane table set at about 30 degrees where it needs to be, 2000 rpm and .52-.60 g/cyl and if i ease into the throttle the timing stays high but as soon as i exceed about 30% tps timing starts ramping down to about 12 degrees.
i have looked all through the tune and cant find anything that would cause this.
os is COS5 02020005

i have set abuse management upper rpm to 5000 and speed threshold to 1.
i disabled axle torque limiting and set max allowed engine torque to 867

does anyone know how to force more timing in this situation?
