TBSS timing problems

May not be your issue, but my stock burst knock settings were pulling timing at WOT with the turbo, so I zeroed them out and it fixed it. It was not pulling much timing though, 0.5-2 deg if I recall.
Make sure you're not in your ECT, IAT, EGR, etc. spark modifiers either.

In .12 sec your MAF lb/min spikes from 1.1 when coasting to 54.x then back to 11.x lb/min once you floored it. All the while RPM stayed the same, this all happened as your TB was opening. If RPM has yet to change there is NO way your MAF reading is going to change that fast. Also, while commanding a 12.6 afr and in open loop your B1S1 voltage is dropping to 70's randomly for no reason while your b2s1 is at 890mv. When the 02 sensor does this your INJ pulse does not change FYI.
