Also known as "Tito Poch", Ramirez was hailed as a racing legend in the Philippines, with a career in racing that spanned 45 years. He began his racing career at the age of 30., beginning as a kart racer, then as a rally car driver starting in 1964. Ramirez began circuit racing in 1969 and formula racing in 1974.
Between 1973 and 1986, Ramirez participated in several prominent Grand Prix races in Southeast Asia, including the Macau Grand Prix, the Malaysian Grand Prix, the Selangor Grand Prix and the Indonesian Grand Prix.
He placed second overall at the 1972 Macau Grand Prix (saloon car), and third overall the following year. Ramirez was named Best Southeast Asian driver during the 1978 and 1979 runs of the Macau Grand Prix.
In 1995, Ramirez established the Subic International Raceway at Zambales. The racetrack at Subic soon became the haven of hundreds of race car drivers who would train there, and would eventually host several international and local racing events.
Ramirez raced competitively until around 2008, when he was 75 and already battling cancer.
Shortly before his death from cancer, Ramirez was inducted into the Hall of Fame by the Automobile Association Philippines, the national authority on motorsports. Ramirez was the long-time co-anchor (together with Butch Gamboa) of the racing show Motoring Today, which aired on the National Broadcasting Network. In 2005, Ramirez gained renewed popularity when he appeared in a popular advertisement for Petron, taking on a driving challenge that required him to traverse 1,114 kilometers across the Philippines on one full tank of gas.
His tag line, "Traffic? Bring it on!" became popular and was widely imitated.
