- BootMod3 (have not heard much about this option, but one of the BMW sales rep. swears by it)
- Dinan (coming soon? And if available, will it be the #1 preferred due to its reliability and non-piggyback approach?)
Note that I put a '?' at the end of my opinions because as I said before, I'm a newbie with this platform and even less experienced tuning it.
BTW, speaking of newbie, the other day I felt like I discovered time travel when I learned that all you have to do to turn off all the electronics in the car after shutting the engine off is push the radio "off" button  |
if you are not running E85, the Jb4 is still a very popular option.
It all depends on whether you want a simpler to install kit or you'd rather spend more time on the install and get more features once done.
