Car stays in limp mode loud turbo noise. HELP!!

Current mods: FBO, JB4, MHD BEF, Walbro LPFP, Have had these mods for a year working as they should.

All started when I was driving and randomly hit the limp mode. I noticed though that the car drives totally fine but as soon as I step on it or am going up a hill, it will hit limp mode and give me a half engine light. The car also makes a very loud turbo noise, very high pitch. I also notice that the idle is a little rougher, it was idling just fine upon start up then bog down then rev up a lot then back down to normal idle. I also got a fuel pump error twice when I shut off the car but I have not got it consistently. I just changed the HPFP thinking that was the problem and still having the same issues. I also took the JB4 out and ran it stock and still had the same issue I checked the codes and got:

2C57
2906
2C90
387F
2774
278C
36BE

Any help or input would be greatly appreciated!! Thanks!!

I had code 2906 the other day and my car was making a whistling sound when boosting. Check if all your clamps are tighten up. That was my issue which caused a boost leak
