I am considering a supercharger but am concerned about transmission and axles (Mojave on 37's, no regear). Has anyone popped drivetrain bits after going FI?
None due to the forced induction that I know of. I've seen on the JK forum some issues but those were 4 wheeling related stuff and had a FI set up. Not sure one or the other had anything to do with did the damage IE you 4 wheel enough hard enough you'll break things eventualy.
The Auto in the JT is rated for the pwoer and trq, abet the tq is at the max rating of the tranny. The tq management in the better tunes, Eddi maggy and Daves should protect the tranny. I'm sure the others are as well I have not read or reasearched enough on those tuns and what they do/don't do to the tranny tune to say.
