lots of testi g showed that those boosyers aro mostly rubish, just few raise octane value but it is never that much, maximum 1-2.
for 15:1 only race fuels or ethanol.
lpg is good idea but it is hard to rev engine above 6000 rpm on pump lpg. again, some special lpgs will allow easy 9000rpm, but i havent seen they are easy avaliable
