After the 2005 season, Sauter and Yellow moved to the No. 00 Haas CNC Racing Chevrolet for the next season. He had one pole and nine top-tens, and tied his best finish of eighth in series points. He made one Cup start that season that year at the Coca-Cola 600, and finished 24th. He moved up to a new Cup team for a new team for Haas, the No. 70, in 2007. Driving with sponsorships from Yellow, Best Buy, Haas Automation, and Radioactive Energy Drink, Sauter had two Top 10s but finished 30th in points. He competed in six Busch races that year with Jay Robinson Racing, but could not finish higher than 23rd.
