With all due respects, the power delivery of the VGT Multijet is much different than the jackhammer blow of the Swift D. It's a linear progression as opposed to the punch-slap power delivery of the Swift . And this needs a bit of getting used to, since linear power delivery is often understood as being "slower". @Srida Can you get any Chennai TFIan(s) to take a test drive in your 90, who themselves may be driving a 90hp Punto/Linea. A few more opinions on the driveability of the car can bring forward a more detailed description and comparison. Also, for a VGT to behave OK and not OK in cycles can indicate a potential niggle with the vacuum actuator. At times it may pull the vanes, and other times it may not (resulting in low performance). So, the next time you visit a service centre get this confirmed. Might help. Cheers.
