1: on motorway i can only get speed of 110 while using O/D and 125 without O/D (But it reduce the Fuel average) so i did't use it for prolong. i oftenly have to drive on M/W and this really frustrate me so please let me know what to do about this. i showed it some mechanic in Pindi he scanned on Computer and told every thing is Ok, he also Cleared the Cylensor, but still same situation.
2: i have 55 kg cylender installed and getting 100-110 in local and 130-140 on long. how could increase the Average and what maximum it could be.
