Feels like cars choking itself

Wot the cars seems to climb in rpm range but hardly any accelaration out of it, feels like its choking on low fuel or something. Tryed it out of the tune still same issue ,weird thing is when I have about 1/4 of the fuel tank left it runs like a beast almost every time its low gas. Could it be the hpfp or lpfp , although am not getting any codes?

It feels like a camry when it does this lol

Might check the gas tank is properly vented. Fuel going out has to be replaced by air or no bueno. The 1/4 tank runs good leads me to vent.

Is it building boost? What's the condition of your water pump? When they go out hidden codes don't allow the car to make power.
