Yes up to a certain point. That is why guys who run race gas while getting their car tuned with a blower end up having problems when they put in regular pump gas. Higher octane=higher timing allowed in most cases.Does increasing the octane allow you more advance?
All thats doing is killing a ton of power up top. You need to pull the most timing at the point of highest cylinder pressure, which is your torque peak. Continuing to pull timing above that simply kills power, which is why BTMs suck ass and are no more than a bandaid solution. You should even be able to put a degree or two back in up top.rammer said:I've set the MSD to pull 10 degrees of timing starting at 4000rpm.
