Thank you for your reply. I went out today in search of diesel pump lab and found one near my home in I-9 Markaz. The guy name was Imran(0300-6067623), he was highly recommended by my regular mechanic. He was asking 8000-12000 PKR, depending on the new part needed to be installed. He said my Pump, Tappet, and I don't remember the name of the third part he mentioned needs to be adjusted. Now my question is, is his quote fair? he said after the tuning the car will give 16 Kmpl on long runs and 14 Kmpl intra-city, I was expecting 16 Kmpl in city and even better on long runs. There are two other shops I found online, one is near Gawalmandi named Waris Shah(+92 51 5530067) and other is in Pirwadai named Iftikhar Shah Deisel Lab (+92 321 5378850) has anyone used their services and give feedback on them.
