I'm glad you're making progress. It's best to make changes to one thing at a time, when possible. Save a new bin with each change and keep notes. Focus on one area of operation at a time, like idle, then light load, etc. As you move to different areas of the map, you'll see trends that will give you an indication of what adjustments will need to be made. Keep at it and I'm sure you'll have it running good real soon.
