Hello guys,

Have a bmw 135i N55 engine, just flashed MHD stage 2+ and made some logs, can you help me with your feedback ?

I see the current boost after 4000rpm starts to drop and it's far from hitting the target boost. Also I see wgdc% is quite high, I wonder if both behaviors are normal due to my high altitude, (Live in Bogota: 8016ft, 10.91 psi ambient pressure). The WOT was made with DSC fully off.

Could it be a boost leak ? (don't think so as it hits 20psi at some point)
Maybe worn boost solenoid ?

Thanks in advance!

Hardware on car
- BMS air intake
- Catless downpipe
- Wagner Evo 1 FMIC
- 6 Eldor new coil packs
- 6 new ngk 2 step colder spark plugs
