Car was making 10lbs. Left the lights on completely drained the battery. Charged the battery up and now it's barely making 1lb or less. I can hear the turbo spooling up a little. Haltech ecu. Does the ecu lose its tune if the car is dead? Drove to work with a turbo fc went home with an n/a.

 

Scratch this post. Just coincidence that it happened at the same time my battery died. Found a coupler had popped off the intercooler piping. Now trying to figure a way to it withought taking the front bumper off.

 

Glad you figured out the issue. Crazy how two things can happen at the same time and have you chasing your tail. Best of luck to you in getting around the bumper to tighten the intercooler piping.
