Looks like your duty cycles need to increase across the low to mid range. Wait for Payam or Terry to confirm, but that's the step I see. Trims are high from mid to high rpm, but they come into control. AFRs don't look bad even with max trims. I'm amazed you're able to run map 3 on just 93 octane. I'm seeing similar logs, but running 96ish octane. Timing looks stable and builds after boost onset. Looks ok... other than lead in trims. Again... wait for BMS to comment, but that's what I see.
