You might have to do this yourself.
Keep a diary , make one change at a time.
Constantly Time yourself , over a given distance ( between traffic lights for example ) & consistently log top speed.
Then you can evaluate if your performance Power / Torque has changed .
Before you do this , you need a clear goal , what are you looking for ?
Do you want more power ?
Do you want more Torque ?
Or a compromise of a bit more of both ..................
