JR Jones Racing builds tune-only HEMI MDS delete calibration files for supported 5.7 HEMI applications after the MDS delete work has already been completed. The base tune disables factory cylinder deactivation logic so the calibration matches the mechanical delete.
Select your vehicle, camshaft, and modifications so JR Jones Racing can build the correct remote tune package.
