Just to follow up… I have updated to 1.0 and did the testing I mentioned. Turn boost was indeed working in 0.9 but in 1.0 it feels much crisper and more reactive. Likely, the dampening effect from the soft start bug. Took it for a trail ride this weekend and it feels great. Up to date here if you want to give it a try.
One major downside is that is messes with ATR pretty bad causing a lot of nose movement that makes the board feel unstable. I can see how ATR works better with turn tilt, but I like how turn boost feels compared to turn tilt. I’m planning on dropping ATR and going deeper into features for the remote to compensate. I’ll see where that takes me.
