You also may have to lower the compression of the engine if you switch to auto fuel.

The volume of fuel required for proper combustion when dealing with different octane's is a different volume. In drag racing we noticed differences between 100 leaded racing fuel and pump 94 Amoco white which is the highest grade. There will be significant differences and no-one should take this lightly. At best it can cause low power, at worst it will cause engine failure through carbon fouling or lean out (depending on which side of the curve you are on). Expect any time you change fuel grade to completely re-tune. In drag racing we found simple temp changes influenced jet settings, mixture adjustments. Please be careful!
