Ok , if you have a boost controller and THAT boost controller is working and Set up , You need to go into the PFC Go into boost pressure , and raise those settings all of them to max and 90%
IF you are using the PFC as boost control , Then try raising the boost pressure ALONE to 1.0 to all the settings which is a bit over a bar . and lowering the duty to pri 60 / sec 64 and see if it cuts out .

injector setting means nothing, except for a trim adjustment to all the maps without touching them, sort of the lazy way.
what you need to know is what actual AFRs were when it began to cut out and what boost setting the powerFC was set to cut out at. if all he keeps saying is the injectors are set to 110%, that isn't saying anything at all. if somehow the boost setting was lowered then it may be going into fuel cut due to overboost(even though you're not even near the factory fuel cut level).
did this person even have a datalogit? or did he tune it solely off the commander? (which by the way isn't a real tune but a hack job with a hammer, it needs to be tuned with a datalogit unless the car is virtually stock)
if the car has very minor mods you may just want to try the stock ECU and see if it cures the problem until you can find someone else or take baby steps to tune it yourself.

Ok your pimvolts are fine . he tuned on the map itself .
on the PFC , I want you to set one of your watch settings as your Boost . and then hit the up button so it shows the max setting .
now I would like you to drive . and boost to when the problem happens .
if possible please tell us your afrs , and what your Commander records as your MAX boost .
I think your problem is that you are hitting fuel cut from over boosting .

the only thing you should adjust is the Boost , raise the settings on the Power FC to max . because the Power FC's boost settings may be getting crossed with the ACV settings and it may becausing to hit fuel cut when you go into high boost .

I Set my injectors on 60 and 64 % and Went with The Boost on 90 % and Set it on .9 Bar on my Commander !!! Should i try it this Way or with The settings i Drove with ???

Im a Little Confused! What do you mean with watch Setting ? Aahh you mean that i Should wach what my max. Boost is on my Commander? And when i press The up Button then. It Shows me The max. Boost right ?

and your injectors leave them where they were .
leave them at 90% , thats the max injector duty before it sets off a warnning I believe . if you set it to 60% the alarm will be on all the time .

yes be careful when you drive the car that you dont over boost . if the tuner did not set the ACVR correctly and it was running off the Power FC boost controller then it will spike so make sure you watch your boost . if you see it go over 1.0 boost then you are going to far. and you need to stop imidiately
Stock injectors run at 100% injector duty at 14 PSI , atleast mine did 1 bar is 14.5 PSI , and because the stock settings on the PFC are a bit skewed 1.0 on the commander is around 15 psi .
i'd lower your ACV to .85 just to be safe. until you upgrade injectors

Also are you running stock injectors?
Yes stock Injectors

I edited my post makre sure you re read it.
But just ot re iterate , on the commander set boost to 1.5
On the ACVR set boost to .85 to be safe .
if you do a pull and it goes to 1.0 STOP let off immediately ( look for this on the commander by pressing hte up button which records max figures ,
on the commander I'd set these parameters up for now
injector duty
Boost
water temp
the last one you can put what ever you want I like using RPMs
I like using hte 4 intead of 8 option because when I put the MAX settings it gives me real time , and max on the side .
with the 8 category option it will only give me either or .

Commander on 1,5
And let the Injectors on 110% and then watch if my boost go up to 1 bar if it does I stop accelerate !!!

if it happens check to seei f it over boosted . if it did not overboost but you once again had the same issue you have another problem .
If it overboosts and it happens you are hitting fuel cut from the ACV and you need to Lower the waste gate duty cycle so it bleeds air off earlier . or take it to the tuner tell him you are over boosting and want it fixed . ( if you paid )
If its jsut a friend tuner who helped you out , Id do some research and lower the acvr duty cycle yourself until you get it right .
