I recently upgraded to a Nissan Micra Vibe 1.2 2015 Petrol from a 2005 Petrol C4.
Something different I notice when driving in low gear (1-3) high RPM (3000+) is without changing the amount of gas I supply or anything else, the car suddenly gets a significant boost in power and pulls me into the seat to accelerate more.
Am I imagining it or is there something more going that I'm missing ?
