Tuning for 94 is fine if 94 is available in your area. If you travel outside your area and only 87 is available then you have two choices: a) Fill with 87 and carry on with no effect on the engine except timing will be retarded if the engine detects knock or b) tow your car to a gas station with 94. I know what I would do.
