Optimizing VTC Index

Is it possible to optimize the Cam Angle Index High, as the High Cam minimum value is is 15º and the maximum is 40º ?
If possible, what points do we need to kee in mind to optimize this VTC Index?

Example:
Current Cam Angle Index High
0; 15; 30; 40; 50;

Change to:
15; 20; 25; 30; 40;

and in the Low Cam Index, as 50º is absent from the VTC Low Cam, is it possible to change the last index ? it will influence the cleaning operation ?

Example:
Current Cam Angle Index Low
0; 15; 30; 40; 50;

Change to:
0; 15; 20; 30; 40;

What points to take in consideration ?

I notice that changing the VTC Index dosen't change the fuel or ignition tables.
Should the main tables be updated ?

You probably do not need to change this, but it all depends on the vehicle and the modifications and what the tuner needs to adjust.
