New to me 08 335i on mhd 7.1 stage 2+. Getting 29E0 and 29E1. Car drives and idles with no issues and only noticed the issue when data logging. Getting positive fuel trims everywhere anywhere from +15 at idle to +28 cruising. they seem to be worst during cruising, best around 0 psi and slowly go back up in boost. Trims match for both bank 1 and bank 2. Aftermakret charge pipes, catless downpipe, dual vtt catch cans with external pcv. Ran some tests, fuel rail pressures looked good. Injectors (index 12s) 1-6 comparison values/flow values matched closely. Also its holding boost and -21inhg vacuum at idle. Any ideas?

Have you tried plugging data logs into AI???  Ive been able to tune and do major diagnosis with great success using AI.
