I'm thinking of rebuilding my C1 with JDM ITR pistons some time in the future to give a static CR of 11.3 to 11.4. I know that it's not a good idea to run high compression without good air-fuel tuning, but then again you can't really dyno tune until your engine has been broken in. So what exactly are you supposed to do to avoid detonation during the break-in? I was thinking that octane booster could be used, but I don't know if it would have any negative effects on the new engine. Any insight?
