I keep going lower and lower each week and I am just getting faster. So yes. I am still playing with timing. On the bench I found that as I went up in timing no load other than the wheels and transmission once I got about 30 degrees it peaked then started to drop off the more I went up. This of course is by the sound and nothing more. I am going to look into a chassis dyno (DIY) at some point to be better at testing different gearing and timing settings just to get some data behind my setting changes
