In 2004 he moved to the Giesse Squadra Corse team, again driving a 360 Modena. Once again, he placed 2nd overall, and was awarded the "Driver Performance of the Year". Part way through 2004, he was offered a position on the Maserati AF Corse team driving their new, GT1 class Maserati MC12, a car he had been involved in developing. He accepted, winning two races that year at Oschersleben, Germany and Zhuhai, China with his team mate, former Formula One driver, Mika Salo.
