CalSpeed & Performance is a thorough and knowledgeable performance shop in Southern California. The owner and all employees are super cool, friendly, very professional, and knowledgeable. Customers report excellent work and great service, with first-class work that they stand behind. They provide honest advice and create comfortable, fast experiences. After dyno tunes and work, vehicles run smooth, better than ever, or like unleashed beasts. The shop is highly recommended, with customers stating they will definitely return for more work and that they trust no one else with their vehicles. Some travel very long distances specifically for their services.
