Exclamation STILL 5000rpm CUT I NEED HELP! QUICK!!!!!!

Hi AGAIN!
Im going insane with my fd. Oce again the mods:
-Non seq turbo
-Apexi exhaust
-HKS Twin power
-HKS filters
-Atkins rotary rebuilded 7000km ago
-HUGE intercooler
e.t.c

BOOST: 0.5bar

So i had this apexi safc2 attached. i got rid of it it only measures the knocking and throttle and rpm changes nothing.

I have tjhis 5000-5500rpm cut off so long that i owned it... runs sturpid rich... it gives codes for TPS and MOP position sensor. it can explain the rich but wtf is this cut. its cutted completely... i have checked the injectors they are 14.9 ohm and all is connected... im really go insane here... i've tried almost everything to stop this thing.. im going to huge car fest next week and its pretty lame if my cars runnin under 5k... ANY HELP WOULD DO?.

I have seen this problem with lots of people but no solution no where...

i ordered plx so i can see if its fuel cut or spark cut... but what ever PLEASE HELP ME!!!????

i wanna belive to world again

Do you think it could be a boost cut issue? I had a similar issue with my FC (s7 engine) and I accidentally turned up the boost on the greddy profec b spec 2 to like 34psi and the ecu ( apexi power FC) said no so at around 4500 when it would normally hit full boost (19psi) it would surge
