Recently my car has been showing me the SES light. When I scan the code with my Diablo Sport Predator, it shows up as air bank fault. This is only when the tune is installed. Without it, the code never shows up. Can anyone help me out here? I thank you guys in advance for youre time...........-Matt-

 

Can you give me the DTC number? I had a similar problem with my cars whenever the Hypertech tuning was installed. Turns out it was a bad cat (common in 2001 cars).
