MHD v BM3 v JB4

Hi all,

I am looking at tuning my g20 330i and looking to get some opinions on any of these. I have never done this before but been doing some reading and the ability to flash back to stock prior to a service is recommended.

I am looking for the most amount of power, in the future I may do the intake / exhaust system however very cautious about warranty.

I have also heard about custom tunes / maps and not entirely sure how that works.

Any advice would be appreciated!

in terms of power out of the box, bm3 and Jb4 offers the most.
MHD is more conservative.

You can custom tune all these options. Jb4 with BMS, Bm3/MHD with third party custom tuners.

Custom tuning means that you are sent a map thats optimized for your car. Your tuner will ask you to datalog, they then make changes to the make for most power/reliability

Completely missed your BM3 offer over Black Friday. Are they likely to come round again?
