I have a 2020 honda accord sport 2.0t, I have hondata tune, k and n intake, and borla exhaust, recently, the car been bogging out, when I drive, the gas pedal feels hard to press, when its in sports mode, I see the gauge for the turbo drop when this bog happens, I hooked up to honda mobile and I seen the o2b voltage up to 4.8 and drop. Is this normal? One day the car stalled and its like it rebooted, it's wierd. Can it be my tune? It bogs down when I'm driving and release the gas and let it cruise, and if I go to give it gas, it feels hard. Idk. Any ideas.

 

Kinda sounds like a vacuum leak. If not then I'd erase the tune, reset the car and start over with that.
