98 Octane

0.58 bar baseline log after fixing alternator and wiring and all boost leaks, new intake pipes, breather kit sorted

For MHD Stage 1 being the only mod on the car besides the rear flap control being disconnected, seems a bit lacking in power at all power ranges low-mid-top end. Engine has had a swap from a 135i N54 but don’t think that’s a cause at all

Trying to diagnose rough idle. Potential fuel problem, DME codes 2AAF and 2DED. New ignition coils and spark plugs.

Car was running well but at 6k rpm I think it overboosted? I got half engine light, throttle closure and felt like i hit a wall.
