You are half right. A diesel motor doesn't have a throttle body. It relies on fuel being injected to the motor and the computer tries to regulate the mixture as the turbo catches up with the air. Most newer diesel manufacturers have a decent hold on the whole mixture thing but when you start hot rodding them its a whole different story. Vw has been racing diesels for years. I really wish this would catch on in the Subaru world!
