I know there are a lot of people here that have much more experience with tunes and companies over the years.

I'm trying to decide which tune would be best for my car (M550i) and for my use. This is a daily driver, and will never go to the track. I do have a dragy and like to play around with that from time to time. I also take this car on long trips with my wife (8-10 hours per day), so it must be 100% reliable.

I've done piggy-back installs before on my 2015 535d and my 2013 535ix and they seemed to work pretty well. However, they are a pain to remove if needed for dealer service, etc. (except the Dinan, of course).

Pricing for my car:

Dinan - $1,699
DME - $1,499
JB4 - $599
RK Tunes - $800ish
bootMod3 - $895 (guessing, not released yet)

I'm looking for the most consistent, easy to use and drive, Stage1 (with the option to go to Stage2 in the future). I'd like to hear any advice or suggestions.
