Few hours ago just bought a 95 VR-II Mini Pajero A/T non turbo.On petrol the performence of jeep is damn slow and on CNG it's worse.Is it the catalytic converter which is creating problem?Because my cousin has a petrol driven turbo charged Mini Pajero and it's very fast compared to mine.By removing the catalytic converter will i gain power?Secondly on the gear box what is (2) and (L)?And the long form of 4L 4H and 2H?And how does it help.Please help!
