They dont, the car wont run right b/c of how picky the ecu is. I have done wrap on alot of cars and never had any problems. But on this ecu the car went wacko. James had the same problem with his when he did it and was not tuned. I am going to wrap my turbo and d/p just not till its tuned with it there.
