In my car, I have forced the change earlier. I am trying to have as much low end torq as possible.
Sometimes I saw dips in the boost curve at the transition, when the car was stock. Remapping helps. I have always thought the transition timing was not right. Interesting to hear you have made an adjustment to bring the LP turbo on sooner.
