I had an issue after installing the 3 stage intake a few days before (turns out I just forgot to plug a hose in) so I had already thoroughly checked all the connections on the intake side. Also I did clear all adaptations already using BAV cable. Is there any chance this would be caused by something on the exhaust side? (a leak either between the headers and the engine or the headers and the mid pipe) as this was the only part I didn't personally do and check myself. It seems too much of a coincidence for it to be something not directly related to the headers as everything was totally fine right up until the headers and tune went on.
