turning back the performance tune for highway trip

[bri60ric]

part #253555, model U7141. I have a 2010 mustang GT. Changes made to vehicle is installing a SteedaCold Air Kit#555-3152 , installing magna-flow axle back mufflers, and then the Diablo sport u7141. I am planning a road trip, do I need to tune it back to burn 87 octane. It is a lot less expensiive to burn 87 octane on a long trip than 93 octane.

If you go back to stock, you'll need the stock intake too....Id leave it IMO.

I'd leave it too. I've made 1,000 mile trips burning 93, and I wouldn't have it any other way.
