Sudden Huge in power

Ours is a grande Punto 2012 model 1.3 75bhp with only 31k on the odo. Lately there was multiple issue due to rat entry like AC blower, speedometer, fuelguage, side indicators etc I got them all repaired from local garage in Bangalore. But there has been a huge increase in power it's like the car torque steers in the 2nd gear and even the 3rd gear there's a huge diff. Btw the tyres are yokohoma s drive 195 section still this 75bhp manages to torque steer in asphalt. The co passenger can feel the slight slide which accelerating in 2nd gear.
What I'm guessing is may be some wiring issue because of rat is fooling the ECU to deliver such power.

Question is will this harm the engine in anyway and will this rat magic power remain forever so that I don't need to spend in any remaps. Btw I don't see any abnormal black smoke as well.

Strange..
At what rpm do you feel the surge?

 

From 2.8 to 3.5rpm

Confused.
Even if the rat bites simulate the tuning box's behaviour of fooling ECU with different sensor values, they are for low rpms for better driveability. Remaps also improve low rpm response, majorly.
Here it appears truly well in the turbo range.
