- Buick Ownership
Deal says 5-30% off their tunes, but I can't find specifics for our 2018+ cars. Anyone else interested? My TourX is totally broken in with over 23k miles and has a good number of fuel economy performance data points across a variety of driving and weather conditions as well as the winter/summer fuel blends. I'd be interested in a tune at 20% off, but I'd purchase immediately at 30%.
