Default Acceleration Issue

I’ve been doing my own research for a while but can’t seem to find anything. If I’m turning, left or right, while either accelerating at a specific speed or if I nail it, the acceleration just stops for a few seconds and I’m not sure why. Any advice is appreciated, thank you in advance.

Update (08/10/2022)
I’ve cleaned the MAF sensor and the throttle plate and put some fuel injector cleaner in the gas tank, which made it run better (as expected) but I still have the same issue. I will try filling up the tank and see if that helps, if not, I will replace the fuel filter, maybe it’s clogged.

Update
I figured it out, it just seems that when the gas tank is around half full it does this, don’t think there’s really a way that I can fix this.

Have you noticed whether the issue is related to fuel level? If it doesn't happen when the tank is full it usually indicates a problem with the in-tank sock/strainer.

Yeah....C4's are notorious for losing fuel at lower fuel levels....in hard turns. I fixed it by upgrading fuel pump...though maybe it was just a dirty "sock".

I’ll try filling it up and see if it’s that, and I replaced the fuel pump and filter when I got it but I will check again, thank you.

I replaced the pump and filter when I first got the car, but I will look at the sock and probably replace it, thank you.

So this may be a strange thought.

Are you sure the ASR is not activating. It will do it on fast turns and hold you back.
