I will be putting my JB4 up for sale soon but have a vacation coming up so not really interested in moving it at the moment. Already sold my X1 N55 for a 2020 Explorer ST because I needed the size.
I think the biggest thing about the JB4 is the codes that pop up on even a properly working car. It used to clear codes automatically but if you are on the current ISO software or purchase a new one, they do not and you will need to do that periodically. Otherwise, power is undeniable.
