Raising these values to say 5000rpm when the coolant temp is hot will encourage pops and bangs during gear change and decal conditions.

it's also doable during launch control:
Adjustments are provided that allow you to enrich the AFR and retard the timing when the vehicle is stationary in order to create pops and bangs. This adjustment is removed as soon as the vehicle starts to move.

The question lies in ethics and liability.
