JB4 is a piece of shit for people who don't know any better. There are reasons you might still want one but not without unusual extra equipment on that bad boy like nitrous.

You stock engine computer does everything a JB4 does but better and more reliably since you're not adding in some extra connections and points of failure.

Go for the MHD, it is a very refined tune with lots of power.
