Over 100 modified maps vs a couple hijacked sensors....yeah.
MHD is the flash tune of choice. Very reliable, customizable, and drives like a more powerful factory car. Ditch the JB4.
There are a FEW special case situations where you WOULD want to run a JB4, but only in conjunction with a flash tune. And those situation would be auxiliary fueling, water meth, nitrous, and weird stuff.
