So was just checking something, and I think that the exhaust flap is closed. I had set the JB4 to map 0 when doing the Cobb flash. I didnt realize the map 0 sets the canflap mode back to stock. I'll have to try it out again tomorrow. I've not yet removed the JB4 since its a pinout harness and a total PITA.
