New F32 M Sport - JB4? Or No?

Hey Guys,

Just picked up a F32 M Sport and am contemplating grabbing and installing a JB4. Reason being is, I bought this car as a DD so I don't put too many miles on my F10 M5. That being said, the F32 is tame compared to the F10. I understand that the JB4 itself wont make the 4 transform into the 5 but I also plan on adding other mods - (DP, Meth, Akraprovic, BBK, and JB4). Think this will get me fairly close to the M? Or am I wasting money and voiding my warranty for an extra 100HP that in the end wont make a huge difference. Thanks.

P.S. I want to keep those AMGs and S models in my rear view mirror

I have a F30 335x drive with JB4, DP, MPE & BMS Intake. I'm faster than my buddy's X5M in the quarter mile.

Wish I had pictures but I trusted my little brother a little too much and my phone ended up in a puddle just outside the dealership. Lesson learned: Never trust 15 year olds with your phone.

Not really.

It idles a bit rough on cold starts since I got the BMS Intake.
Started going away as the weather started to warm up but it seems to have come back since loading the new firmware (8.8) and running map5.

It's really a minor issue that should get fixed with a bit more development.
