if you see it go 13.1 then its time to let off as well this is under boost ofcourse .
the higher you go say from 0-5 psi you can do 12.5 afk , after 5 psi you should keep it under 12.5 between 12.1 to 11.5 at .85 bar
now the injector duty .
on the commander there is an option to view injectors jsut like you can view boost pressure . then you select that option it will show the injector duty .

Ok will try it out
So on my power fc I will set the setting on 1,5 bar boost and 90% duty
And the injector at 110%
On my avcr I will set it on 85. Bar.
Will see what it does when I hit the gas and will let you know how my afr, max boost and max Injector duty is

Just tried it !!! I got this setting! Power fc boost 1,5 and 90% injectors on 110% Apexi avcr got my boost on 80% Got max boost .85. But just once !! then was the max .55 ??? duty about 85% And afr is about 13-14

you first boosted .85 But that only happened once ,
then you only kept boosting .55 and your afrs are at 13-14 under boost?
also did you get the same ignition cut over 4k rpms as you were before?

Drove the car further about 15-20 min. And kicked again and only got max. .55 ??
Yes under boost got that afr!
I changed my spark wires new ones got 0.25kohm but my old one had about 5,5kohm no didn't get the engine cut at that boost
But after I boostet .83 I looked at my avcr and the duty was on 30 % is that maybe the problem ?

adjusting those tables pictured will lower the injector trims, if it was originally 110% and lowered to 100% then you just reduced the amount of fuel by 10% which is nearly a full point of AFR leaner.
i suspect the tune is lean based on your figures and that the boost controller is not set up properly if it is switching to a lower duty cycle when the boost drops off(scramble switch? or it is setup with a gear judge which should just be turned off).
you can do wide range adjustments by upping the figures later in that table at 4k and beyond but it isn't an ideal way to tune an ECU. you also have to be sure the injector duty cycle isn't reaching maximum, it should be only reaching about 85-90% at the upper end.

yes , I doubt this is the problem .
like Rotary evolution said , Set the injectors back to what the tuner set them to . originally And yes the duty cycle on the ACVR probably needs adjustments . if the Tuner does not want to fix this . Then you will have to up the duty cycle on the ACVR , NOT INJECTOR DUTY , But waste gate duty cycle . until you get desired boost. ( be careful and do this part slowly also this part should only be done AFTER your lean issue is fixed )
IF AFTER you set the injector back to what the tuner had them set to you are STILL lean please let him know this . and if he wont fix it and you paid him for his work . I would REALLY SUGGEST you never see this guy again.
I could not live with myself if I left a car in this condition

The problem is I'm in Austria and there is NO TUNER around!!! The tuner comes from England once in a while!! We ship em in because he is really good the distance is the only problem !!! But I will ask him on Facebook!!

Tem120, I set my setting back like on those picture I've been taken!! Would it be to much if I set the boost on avcr on .9 and the duty on 75%

Yeah gotta see what I can do I will let you know if I got something !! But thanks very much you helped me a lot !!!! I guess that my spark wires was the problem! I just need to know what the tuner set on my avcr
