Also log IAM (or whatever Cobb calls it), Feedback Knock Correction, and Fine Learning Knock Correction. The ECU may be pulling timing due to knock at the CL/OL transition. The stock 04 STI's do this often from the factory, and it is even worse with mods on a stock map. It is enough to feel it sometimes, and that would not be good for a new engine... or a even a broken-in engine.
