Do a search. Lots of info in the 1st 3 pages of this section.

@BimmerLover98 , what is your priority?
Warranty is the issue and price not an issue, then go with Dinan.
Price, power, and flexibility are the issue, then go with BMS Stage 1 or JB4 Stage 2.
Gain wise, you have to read around. Dinan is gaining popularity, but majority still leaning toward BMS. PM me if you need help, I am local to you.

Hi,
JB4 offers more power, more features, flexibility and free software upgrades.
It is also the most popular tune and you can get support from thousands of fellow forum members.
Dinan offers warranty in case thins goes south ( Highly unlikely with either tune )

Then you also have aFe scorcher (plug it in and forget about), RaceChip (tweakable from unit itself), and Active Autowerke Active-8 Tuning Box

All the above mentioned great rep, proven but it all depends on the individual needs.
