yeah have been advised dont get more than 10.5:1 comp ratio, have pulsar e15 electric dizzy so better there, might need to upgrade coil for a bit more spark but lpg must meet equivelant of 110ron octane as min so better than 98 ron pulp

The last I heard the minimum industry standard for lpg was 94ron. 100% propane is approx 110ron. But with less enerfy per burn cycle than blended propane / butane.

in wa our gas comes from north west shelf . you get whatever comes out of the ground. if your lucky they filter the pebbles out for you.
my point is keep some safety margin in your tune up regarding boost and timing because what you get one week may not be what you get the next week
