Somewhat curious about trying out this tune. I used to have an n54 and know how tunes and warranty work. Does this tune throw any tuner (shadow) codes that the dealership might detect? I believe the ecu records the highest rpm the engine has seen. Wouldn't raising the rev limit void the warranty for sure? Just trying to see if the little bit of gained hp is worth giving up my CPO.

TIA
