Help please mk5 Jetta

Hello am new here, recently I removed my dpf and put on a full straight through, I got the dpf and egr mapped out, during doing this I removed my turbo just to check it, I replaced my turbo and actuator but now if since I done this when the car comes under pressure at low rpm 2000-3000rpm it puts on glow plug lights and loses power, I’ve replaced to following things turbo, actuator, maf sensor, boost sensor, boost solinoid but still no luck, any help would be great thanks
It’s a mk5 2009 jetta 1.9

If you did not get the codes read then you are relying upon luck.
Get the ecu memory read and maybe someone will be able to help.

I got the person who remapped the car to scan but there was no codes showing
