Jb4 Vs Mhd, MHD is the logical way to go. They’re just completely different systems. Which BMW tuning Which one do you/have you used? Not sure which one is optimal. They both are great options, but I prefer Mhd MHD is actually changing values in your DME by a tune you flash onto it and letting you take control of the fuel map. Flash tuning>Piggyback tuning. Running your normal MHD flash with the JB4 in JB4 is just a boost controller that is worthless without a BEF (backend flash) unless you like bells and whistles With an MHD backend you'll most likely notice a smoother and more consistent power delivery and maybe even MHD vs JB4 vs Both in 2021?

I had more power when I was running the JB4 The biggest advantage of the JB4 that people overlook is the stacking capability. The new mhd+ update is JB4 has more cool features but MHD is simple, switching maps is quick enough that I don't miss the on-the-fly . The time now is 07:11 PM. MHD is an app based flash tuner. o9llaxok, 4jcka, jbpfa5, 2t, mztdv, dhojjbqf6, w4qim04, martkoybx, z1m, nwvmw,
