Hi just installed sequential lpg in Punto 1.4 emotion pack petrol. Noticed follwing things:- 1. Engine noise has changed became slightly more. 2. There is no problem but the engine pattern has changed like getting high pickup at low rpms at 1500 rpm like maruti cars but smoothness has gone. Earlier i got pickup after 2000 rpm and engine was smoother. Earlier at idle condition engine was at 1000 rpm now its less at 700 rpm. I am not getting any problem like jerks or engine stopping on LPG. While running on petrol also I am experiencing these changes. I want to know if LPG calibration changes the original engine running pattern? What to do maintaining the original engine running pattern on LPG?
