Plz help, the problem i am facing is that i have tuned my 2006 xli from a local workshop.
Before tuning my car is doing approx. 120 ~ 130 km per cylinder on cng, but after tuning it is doing only 87~90 km per cylinder. Besides the owner of the tuning center claims before tuning that my car would touch 160 km per cylinder.
Now plz let me know what thing goes wrong and how to rectify this problem?
Many thanks in advance.
