I use similar to the hobbywing settings. See thread

If I remember correctly turbo comes in at full throttle and boost during acceleration (or the other way around).
For normal conditions try
10 Boost Timing (currently set to 0) - 8 to 10
13 Turbo Timing (currently set to 10) - 12 to 18
14 Turbo Slope (currently set to 24) - set to 3deg/0.1s
Also drop punch to 1 or 2. It is probably still at 7!!
Start from there and I bet it will feel a lot smoother. I'm assuming you have something like a 7.5/8.5 motor there so also check your gearing.
