Guru, driving a car with a turbocharger , that too a fixed geometry one , has its own pros and cons. One of the cons is that the turbo takes its own sweet time to spool up and provide max or closer to max boost which translates into more power. And one of the symptoms you've described seems to be a classic case of turbo lag. ( as if driving with handbrake on) Assuming that your clutch settings are ok and no problem there , it is always a good practice to let go of the clutch slowly and smoothly, rather than suddenly. It saves a lot of stress on the engine and the drivetrain ( gearbox , drive shafts etc). The more you drive your car , the more you'll adapt your driving style to it. Try to change gears based on the feel you get from the engine and the accelerator pedal rather than by looking at the tachometer. Thats one way to feel the car when driving. As far as possible try and keep the engine in its powerband. And change gears accordingly. So that you can have instant power on tap when you press the accelerator. Again i'll say its all about adapting. However , if you do feel that there may be a problem in the car , do get it checked and ask the service centre guys to arrange a test drive of another Punto MJD so you can have a comparison. Gud luck Gurjinder.
