Welcome to the Southern California Tuned Port Injection Organization

The SoCal Tuned Port Injection Organization was founded by father and son team Don and Kevin Lorentzen as a way to further promote and advance the Tuned Port Injection engine. We are a fun, friendly group of people who want to get together and share our love for the 85-92 Camaro, Trans Am, and Corvette, as well as other vehicles of all years who have been converted to Tuned Port Injection.
