Leave the settings where they are for now. Do some logs and send them to the guys over on N54tech. They’ll read your logs and tell you what adjustments to make to get the most out of your JB4.

Agreed on the chargepipe. Mine blew at 51k miles, which was about 3k after I installed the JB4.

My charge pipe too blew after 50k+ miles with a jb4 installed; dealer replaced under warranty. I've now registered about 80k on the jb4 (no bolt on's). The only issue I have is sometimes the car will not start which didn't start happening until roughly 65k miles. I must disclaim I cannot directly attribute the issue to the jb4 however....when I remove the jb4 and attempt to start the vehicle a hand full of times, it'll finally turn over. When I take the car to the dealer, they show no codes (and take my diagnostic fee).The issue also does not replicate when the device is not installed. Personally, I feel like its a fuel pump issue just by when the car errors out and the sound it makes when everything is priming after its unlocked; but who knows.

With that said, I love the jb4. I'd feel a lot differently about my 435 ownership experience if it were not available. Enjoy it! (map 5 all day).

Map2 should be a good starting point for that setup.

I know your OP was 8 months ago, but a 2014 335i that is PWG?

They are usually EWG but his production may be 2013 and on the cusp of the changeover.

He never posted again because his charge pipe broke and he's on the side of the road some place.
