take your chip off the car. warranty or not, you should still take your tune off when you go to dealership, so that they don't flag your cars in their system.
software probably would not upload onto the car's ECU without the tune off anyway.
and no, the new software that supposedly be fixing the hpfp problem cannot overwrite jb3. since jb3 is a hardware based piggy-back tuning chip, not a ECU flash. you need read more on the engine tuning section this forum so that you don't mess anything up in the future.
