Same goes with the CAI i went back over all my connections. It could be like ShowStopper said a little too much taken off from VMAX may cause the issue and even with a good CNC machine anything can happen. Having a stock tune dosent help but i dont want to lose my warranty.

Hello V6 LS Supercar,

Have you considered visiting a dealer to see if they can pinpoint what the issue is? If so, we are able to set that appointment for you to save you some time. We would need some information from you which you can private message me. Here to help.
