Really appreciate the data!! Very interesting. So it looks to me like the stage 0 is still holding back the engine quite a bit (still). AFR targets are starting 15 down to 12.5, boost is held back to 16.8, run is super clean and easy. stage 1 is now looking for afr 12.5 to 12, boost 21.8. Also looks like stage 0 is trying to modulate torque with the throttle angles, stage 1 is full beans. Stage 1 also has another degree or so of timing across the board.

In both cases, no knock, no HPFP target miss, no problem with LPFP, nothing that indicates engine is anywhere near the limit. What I've noticed in many dyno logs of these motors, is if anything the turbos spool faster than the ECU can hold them back resulting in some weird stuff in the 2500-3000 range if you go 100% that low. nothing major, just some power output oscillations.

Stage 1 93 oct might be just what I'm looking for.
