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?
Thats kinda like a myth thats been proven wrong for years here. Its not too smart for a company to design a chip that will be simply overridden by AF sensors. What would be the point then for 225 USD chip?
