Hey guys,
I've been battling this for the last week. During partial throttle (log shows throttle easing into WOT), I'll get 6+ degrees of a timing drop. Sometimes it goes from 12 to 6, then back to 12, other times it goes from 6 to 0 and back to 6 almost immediately. You can definitely feel it, and its annoying and likely bad for the engine.
The log is with a Cobb/Procede stack, but it happens with Cobb only. I'm not a Cobb guru by any means, but I don't see any tables which would pull timing that much except for:
1) Unk Base Throttle Safe
2) Unk Throttled
Thinking it has something to do with these tables, why is the DME kicking into what looks like failsafe tables? It happens at maybe 2-3psi and 14* of timing, nothing that the engine cant handle.
Something is awry. Any help is much appreciated.

Edit: Basics:
1) Cobb is basically a stg 0 ST Cobb map with Vanos, timing, fuel and fuel scaler controlled by the DME. DME targets ~12 PSI
2) Procede is adjusted typically, no fuel bias, minimal timing control on Map 1 only, meth control at 16ish PSI.
