Hellcat 2015 No Charger Loading

[ogrosgarage]

Hello my friends, my name is Lucas and I live in Brazil...
Here I built a 1969 Charger with Engine and Automatic Transmission donated by a 2015 Hellcat.

I managed to get the set working a few days ago using a Mopar controller and Sound German.

everything was going well, car with ok power and ok supercharger... however today I started it in my garage and noticed that I was no longer hearing the classic sound of the hellcat supercharger and the car was limiting at approximately 4500 rpm, I used my scanner to I read the ECM errors and noticed that error P0171 appeared, it says that the fuel system is poor, but I just changed the fuel pump and it's still the same, the car doesn't even seem to have a supercharger anymore, it's not charging anymore and it is limited to 4500 rpm, I have already tested injectors, spark plugs, cables, air leaks, changed the fuel pump and even so the car is still the same without power, without charging the supercharger and with this error

Welcome to the forum.
Sounds like a great project. Unfortunately, I don’t have the expertise to help. There are smarter people here, though. Hopefully, one of them will have the answer.

I would check the volume of the fuel pump you're using and the size of the fuel lines. Do you have a fuel pressure regulator? Fuel return line?

When you say doesn’t seem to have a supercharger can you not hear the wine or does it feel like a lack of power? Do you have a laptop or a professional scan tool? Monitoring injector duty cycle or fuel pressure should be where you start. Especially if you have fuel codes.
