For me, i'm wondering how to launch properly the car to get a good 0-60..
I have a 435I 2014 convertible with heavy wheel (Vossen cv4) RWD Automatic with FBO :

CTS intercooler
BMS Intake
ER Chargepipe
ER Catted downpipe
Full borla ATAK catback
JB4 + EWG connector
Running 94 octane on map 5! Will do a custom map 6 soon!

I've tried the Launch control and can't even have a little grip so car is spinning like hell...

What do you guys suggest? Brake boost only? 2000 rpm? less or more?
Starting from 1st or 2nd gear?

At what RPM do you suggest to shift?

Waiting for your experience and news!!

We have similar setups, i'm in a 355xi however. I've only been to the strip once, I started in 1st gear, sport+ and break boosted to about 2-2.25k - then I was running on stock 18's and all season run flats (less mods than i currently have listed). I was high 12's on average. I did some runs with shifting at redline and some at 6.25k-6.5k going into 3rd+ and did not notice much difference. I boosted up to 2.5k once and all tires spun and I hit a bad time, i think 13.3 seconds on that one. I don't have jb4 installed, but one thing I think you can do is set boost @ each gear which could help you out with launch in 1st and 2nd with low psi.

I had some issues with delays after shifting in higher gears which i'm still trying to work out so it should have been faster.

After adding the new wheels/tires (Michelin PS4S) i've had no tire spin issues and dropped about 3/10 a second off runs
