Turner Power Module or JB4.
New to BMW not sure which is better and are there other options out there that I am not finding. Also what are the best supporting mods I should do as well.
thanks
I'm definitely not an expert but been looking into this for my E82. So far many people have told me to check out MHD https://mhdtuning.com/
Seems to be one of the cheaper options, requires just an Android device and a good quality K+DCAN cable. They have few good tunes for the B58 engine.
I'm using MG flasher, currently on the OTS stage 2.5 map, couldn't be happier. They offer the same HP/TQ output as MHD, plus the on-the-fly switchable map and max cooling options. And I'm also satisfied with their same-day reply customer service so far.
