I'm not a racer or tuner but I'l like to get the info in case I outlive my warranty, wouldn't a tune make up the difference?
my post was mainly in jest.
But from what we know the JB has a tune modification from a red eye which increases the redline for one. No one knows what else maybe timing? Who knows. Also there are posts saying the newer cars including the JB have different COT settings and pull timing much more liberally than earlier cars.
Eventually someone will DL a JB tune and a red eye tune and figure it out. I’m sure a red eye can be uploaded with a JB tune no problem.
From dodge it plainly says a JB has a different engine calibration.
all that being said though if your changing your tune you should get a custom dyno tune which would maximize power over any of tje stock canned tunes.
