They said they did a trim height relearn. Also an alignment.

Do you have the alignment report before and after.

I see nothing in hptuners so i guess it has its own controller.

Federal law prohibits new car dealers from working on vehicles that do not meet the emissions standards in effect for their year of manufacture. Obviously, some dealers follow the law more closely than others.

The other part of the problem is that all of the controllers and computers in a car are interconnected, and if you reflash or reprogram one you may have to do them all, which can take 6 or more hours.
