I've heard diesel vehicle owners claim the efficacy of additives like Bardahl towards making their engines more responsive.

Where did you get the engine overhauled? I am starting to suspect the quality of job done.

Or have you changed the compressor to a larger one?

Also, get your clutch and fuel pump checked.

i got the total ac over hauled with compressor changed at maruthi service station which costed 19k total .
And about the head over haul i got it done a year back.

Is their a problem with the fuel pump do i need to get it tuned so as to improve the pick up??

Does you car emit black smoke alot. If the answer is yes then there is surely a problem with the fuel pump.
