I started to have a few problems with the car. Nobody could understand them, not even Suzuki people.
Well after a few months it was resolved, and it was caused by CNG.....
I have driven both the Rxi and Lxi models, and they cannot run like Sports model, not sure why.
My advise to you:
1. If you have money for petrol, dont think bout Cng,
2. If not, Install ORIGINAL Landi Renzo kit from a good place, even if it costs a little extra,
3. If you do get problem in future, guys here will help you out
