My friend patroler,
its not just the cng setting that gives u economy n performance. first get the mechanical as well as the electrical system absolutely DISEASE FREE. Missing valves, improperly set tappits, hypofunctioning plugs and electrical coil do give a hard time with cng. Landi renzo franchise is a good option. keep in mind that a very good acceleration and too outragious performance on cng means a compromised average and a very good average means a bit compromised performance.
