I was just wondering if your fuel octane can ever be "too high". Assuming you have full control over your timing and fueling, does it ever make sense to use say 100 octane when 110 octane is availabe at the same price? Does higher octane fuel always make you lose some power (even after re-tuning) ? If so, about how much? Thanks.
