As long as the power boost is not completely out of this world, I wouldn't worry about this too much. The drive control system doesn't have a fixed, pre-programmed answer for any given power balance situation in the standard setup. It goes by sensor read-outs - wheel spin, steering angle, pedal input, ... It reduces front and / or rear wheel power if it detects a potentially unstable situation, reads the sensors again, corrects again if necessary, and so on. Several times a second.

If there's a little more power from the engnines, the computers will see it as a slightly slippier road. Nothing more. So, deepnding on what tires you run and what road you're on, you may find the stability control to show its face more often in low grip situations with more power being produced.
