I have a 2013 ZL1 I added a Diablo tuner and a cooled air system, I just used the 92 octane tune only no parameter adjustments made mostly because I don't know anything about engines , the check engine light comes on when the super charger starts adding pressure . The turner only tells me that bank 1&2 is lean the mass air sensor is out of test range. Please can anyone help ,I don't know anyone to take the car and tuner to, to get the car set up properly also to let you know when I put the stock air intake with a K&N filter the light does not come on. Any help will be greatly appreciated ! Gary

 

Did Diablo specify that the tuner was designed to work with your particular engine? I suggest you take the thing off before the engine is damaged. You really do not want a supercharged engine to run lean.

 

Thanks! I did talk to the tech at Diablo and they said it was for my car but the setup from the factory was for a stock ZL1 and I would have to make adjustments for any mods I make to the car as it came from chevy. He didn't say anything about it would damage my engine ! I took the cold air system off and put the stock air system back on with a K&N filter and the light hasn't came back on and car is running good it just doesn't look as good when you raise the hood to show the car, I think I'm just going to live with it the way it is, but Thanks for the advice .gary
