N75 fitment...can anyone confirm? picture inside

[Chlippo]

after the mecanic installed the silicone tip i noticed that the car is not boosting properly. Before diagnosing anything i thought maybe the N75 is fitted the wrong way. so here is a picture.
Boost comes late, at around 5500 i have 0.8 or 0.9 bar on my boost gauge.
AFR gauge is always 13 to 14, i am not used to audi's yet but isnt that lean?
car is a 2001 S3 amk engine. 3" downpipe and exhaust manifold. going for a remap on monday.

Difficult to tell from that angle but it looks like the longer outlet is going to the the TIP which is right... there shouldn't have been any reason to remove the other pipes from it if just doing a TIP change...

Proper configuration for a std N75 valve is boost in the bottom, long outlet to the tip, shorter outlet opposite the longer one to the actuator...

As for not boosting... is the car mapped yet? assuming not then 0.8/0.9bar is about std boost... AFR on a std map is lean... they are designed for economy rather than power... its not dangerously lean for the boost level though...
