race fuel mix in a dd?
Will mixing in a couple gallons of 100+ octane mess anything up? I don't have cats and the O2's are tuned out with an otherwise factory tune.

There is no reason for on anything that runs on a factory tune(making assumptions about your combination based on this fact). I'll explain it, then just paypal me the extra money for saving you money and not losing any power...
High octane fuel does not make any more power(or have any more BTU content) than pump gas. And is a complete waist on an engine that doesn't need it.
In fact it can hurt power because the higher octane helps it resist burning. This means it takes more total time to burn, which equates to likely more spark timing to burn it completely to get the proper push on your pistons to make power.

Guess I should have been more clear but was in a hurry. A friend has a couple gallons left over and offered it to me to get rid of. I'm not looking for extra power, just want to know if I mix a little here and there if there are any detrimental effects to any engine sensors or such. As mentioned above I am not running cats and my 02 sensors are tuned out. I figure if its blended with 93 its going to end up under 100 anyways.

you should just sell the couple gallons to someone who could use it and keep the money or run 87 and add it to kick the octane back up and pocket the difference. why woud you add it to 93 if its not gonna do **** but cause problems??
