Whistling noise and rough revs in LLT after crash

I had a frontal crash with my 2010 LLT v6 three months ago, initially the engine was not affected, only a few notches on the A/C condenser so it was replaced. They gave me the car yesterday.

The car is stock except RX catch can (the drain valve was open when they returned my car) MRT v2 and vitesse throttle controller (Always SP0 after the crash)

These are the symptoms:

-Digging sound at idle, disappears when i press the clutch.

-whistling noise which increases as you accelerate, it sounds like a turbo or a supercharger, especially around 2000rpm, only disappears when you step slightly on the throttle, like about 10%. If you accelerate more or lift your foot off the sound becomes.
The A/C doesnt affect the whistling.

-From 1500 to 2500rpm the entire car vibrates, especially when decelerating at 1800rpm. It feels and sound very rough, before the crash the reving and deceleration was smoother.

-No check engine light or messages

Any thoughs?

Thank you for your help and sorry for my english...

Sounds like it needs to return to the place of repair and talk to them about those symptoms. Good Luck and keep us updated on what they find.

Hi, the motor mounts seems to be bad, maybe the engine its a little angled and this is the reason of the noises.

Ill keep you updated when they replace them.

Thank you!
