You can put it back to stock and take it to the dealer they might flash a new tune, you can then update your AP to the latest version and flash back your tune.

Make an appointment to get the recall addressed. IIRC mods or not they still have to do the recall due to NHTSA rules. Drive it to the dealer, when you get there, flash back to the stock tune. Afterwards flash back to the Stratified file before leaving the dealership.
