Anyone who uses a JB4 in place of a regular flash tune is misinformed and victim of an inferior product. JB4 could be useful for exotic things like auxiliary fueling, nitrous, water meth, but are you running any of those? Even in that case, you would COMBINE the flash tune with the JB4 for best performance and safety.

In conclusion, ditch the JB4 as fast as possible and get MHD.
Oh my gosh you people are the worst. Did you even read my post? My goal was to run JB4 and MHD BEF. I've spent hours and hours researching whether I wanted a JB4 or not. I wasn't asking whether to keep it or not, I was asking for help with my situation.
