In the past from what i heard is that after the tuning, you will be able to feel the gain on power and torque. After couple of weeks, the engine will re-learn and adjust the fuel map to over-write the Unichip map and therefore the power & torque will be back to square/stock one.

Is that true?

It simply is a piggyback that modifies the crank signal (to adjust timing) and MAF signal (to adjust fuel) to the ECM. The ECM will still see the output changes via the AFR sensor and will eventually trim out the changes.
