I talked to Lee at C@L, and this guy really knows what he's talking about when it comes to tuning the C@L System. With the performance mods I already have, he recommended taking the Predator Performance Tune OUT of my Mach 1, and going back to just the factory tune. He said when I have my Mach dynoed on Monday, to do 2 pulls with just the factory tune and look at the real-time data of exactly what timing your car is running. You'll go to "Custom Tune" and add 4-5 degrees of timing based on what your car was running in the real-time data from your dyno pulls. For fuel, you'll go to Factory HP tune, "Modify Tune", go to WOT Fuel Adjustment and you'll richen the car up in the 2K-4K range, and then richen in the 4K-7K range also. Your ideal A/F will be between 12.8-13.2 range. End of drama.
