Comfort mode faster with JB4

PhilG20 · 07-15-2022, 11:52 AM

I recently installed JB4 on my 2019 330i. I have been driving primarily in sport mode. However, on YouTube I saw video of a xdrive m340 dyno and they were getting more power in comfort mode and were running JB4.

So a little earlier I did a couple pulls in sport mode then switched to comfort and did a couple more. Well it definitely felt like it pulled harder in comfort mode. It was a noticeable difference.

Has anyone else experienced this?

Makes sense if boost is increased right?

What do you mean? Why would added boost improve comfort mode more than the improvement in sport?

Regardless of mode - your turbo will spool quicker at a higher PSI. Try using draggy times to really see if sport is faster.
