True, But i know wit my friends camaro, tpi and running 10:1 pistons, on regular gas you never hear a ping or knock or anything, it runs beautiful. its just because the knock sensors and computer are fast/good enough to prevent it. but like you said there is power loss...so it does help to run higher octane if your compression is higher than about 9:1. But my point is (to others) that just because you dont hear the pinging, doesnt mean its not retarding the timing.
