My 2011 has never had the gps updated. It is time to get that done.

Does anyone know for sure, if having the gps updated at the dealership, will infringe on the Hemi Fever tune.

I would recommend if you ever bring your truck in to always revert It back to stock just to be on the safe side.

No it will not interfere with the ECM.
