So I just installed the PTuning v2.2 kit with my preexisting Edlebrock kit but I am having issues with voltage drop right after installation. While idling and accelerating, the voltage drops to 12v but while coasting it stays at 14v. However, the car drives normally with no issues. I haven't connected the PTuning harness at all but only the fuel lines. The reason for this is that I haven't installed the injectors and started the retuning process with CSG yet. Why would installing the fuel lines along with mounting the ethanol sensor and box inside the cabin cause any electrical issues? The harness isn't connected to any part of the flex-fuel kit or even on the car so I'm not sure why this would happen.
