The MHD just seems even easier to install the map and is cheaper (initially). clearly with as big a following as the JB4, though I don't like the idea that it flashes the ECU and I'd need to install the stock map which takes a bit of time (40 odd minutes).

Anymore advice or information would be massively appreciated. Looking to invest later this year

Thanks for the info and sorry to thread jack

older post but, MHD is the way to go for N54 tuning. MAP switching on MHD takes some 60 seconds. MHD is more reliable, and way more consistent. i always say this...

JB4 needs a Flash to work 100% but a Flash doesnt need a JB4 to work 100%. And with all the upcoming features about to drop for MHD only. yea, just do it, lol
