JB4 *could* be useful for running auxiliary fueling, nitrous, meth, or some crazy stuff of that sort that the ECU can't control. If you want to run meth, fine, but high ethanol gas mix gives same power with considerably more safety if your fueling is there. Meth also has inferior drivability at part throttle, even with the best progressive controllers.

If you're not doing any of that stuff, the jb4 is a joke on you. I want whatever is best and I've been remapping cars for 5 years now. How long have you been remapping lol.

Also, curious how you mention every lame tune out there but not the gold standard, MHD. Try MHD, you'll love it.
