B48 320i lci with JB4

[dannyvdberg]

Hi all,

Ordered yesterday the JB4 for the b48 engine. This is the only option so far because the DME can't be hacked by any tuner..

Hopefully it will add enough HP and NM to the car. I did a dyno with 98 octaan. Results: 196hp and 286nm.. I don't know what to except with JB4. Hoping around 260hp and 400nm..

Anybody else here already with a B48 engine and JB4?

Thank you!

What were your results with the upgrade?

@dannyvdberg would love to get your feedback. Not a ton of B48 tuning info out there.
