Old school recommendations was to lower your static CR for boosting so you didn't get detonation (knock). 12.5:1 + boost was unheard of years ago. However the DI on these cars and a good cylinder head design does a wonderful job of preventing this. E85 does even more to help with its 107 octane, 40% more liquid in the cylinder and the cooling effect of alcohol evaporating. If you were running e85 I'd say go for it.

The more CR the lower the boost. Lower boost means a smaller turbo which is a good thing
