It's only rated at 87 octane, so that gives you more room to utilize higher octane if necessary, like when using boost. I'd say just look around on forums like cobaltss.net or sky/soltice forums and we can get an idea of what we need to boost the LLT.

what is the cr on the cobalts/sky/solstice motors that are fi tho?
