I am planning about Tunning/Service of my JDM Wagon R. I bought it back in december 2015 and its meter was on 24000KMS and i have driven it further 15000KMS only by changing engine oil Havoline Formula and air and oil filters and without any kind of tunning. There is no problem at all but i think after 15000KMS a proper tunning should be done with car. Am i thinking right or wrong? If yes then can you suggest me any proper tunning shop for JDM Wagon R in Gujranwala or Lahore?
