octane isn't as big of an issue as fueling for boost. you just need to keep afrs in control. you can run a lot of boost and less timing to make similar power.
boost limitation is based on fuel cap
timing limitation is based on octane
both have an efficiency range where going past the peak point will not make more power or could lose power.
