I run MHD+ with a Reflex unit, and I can't think of any reason to have a JB4. The Reflex offers sequential PI and ethanol capabilities along with great boost control for single turbo cars in combination with MHD, which, as Saif said, has anti-lag and on-the-fly map switching. All the things that used to be JB4-only are starting to be available on both platforms.

With all the problems people have encountered on JB4, I'm pretty glad I didn't go that route.
