Mehran is a regular CArby car, computer tunning for such cars isnt possible, but we have a set of procedures to improve performance on CNG , otherwise if u want to check the exhaust ratings etc go to Enercon, but if u have a Mitsubishi Evo VIII, Prado, Landcruiser etc come to us or bring any OBDII car (except Vitz , Baleno) can be thoroughly checked.
MIL Light Deactivation / Removal of Fault is also provided at our place
