For best mileage improvements, install the 87 tune or Performance tune (for 93 octane) and go!
The tunes are all designed to improve mileage by 1-3 mpg on the highway.
Keep in mind that driving style is the biggest contributing factor in determining how much mileage you get, so drive sanely!

The U7198 will work on your brothers Vette, but it will only tune one car at a time, so you will have to restore the stock tune to the Yukon before you can tune the Vette.

Thanks
