Saw this interesting customer DCT/335is log yesterday. The shift spread is super tight and the JB4 boost control very good with it, even with the default map and adaptive PID disabled. But what surprised me most about it was the factory boost targets. Of course the JB4 will ignore the factory target now with its new absolute targeting system but I was surprised just how low the OEM boost target was during these runs. Almost identical to a normal 335i! I expected at least 12psi based on what I've heard if only for short bursts but saw nothing over 9psi in the log.

It does reach 10psi. Here is a graph of mine (I had the Power Kit).

I wish I knew how to read these stupid graphs!

My jb3 logs are on the other forum and I was sustaining 12psi stock. Got to 14 with T. Broken logging or broken 335is. Mind you my ambients were in the mid 90s.
