Is it possible that the TPS or APPS could be going bad?

I just replaced the map sensor and I took the truck around the block and I didn’t notice any difference, if the map sensor was bad should I notice and immediate difference after replacing it?

I just did the fuel filter and air filter, I have a 4” turbo back straight pipe, is there anyway to check if the turbo is bad?

What could be causing the turbo to be loosing that much boost, I checked all the spots that would cause a boost leak and I didn’t see anything

The truck is running fine, it just feels slow. And I’ll clear them and check again

My check engine light isn’t on but I flipped the key a bunch of times and these are what showed up, p1693 ,p0523 ,p0122, p1694, p1687

Need some help, I just put a boost gauge in the truck and I noticed it’s only making 5-10psi. The RPMs are near 2k to hit 10 psi. The turbo sounds like it’s spooling like it should, I checked for boost leaks but I couldn’t find anything out of the ordinary. I know these trucks aren’t meant to be fast but it shouldn’t be as slow as it is now.
