Gas pedal delay
Some times in some situations i need to press pedal full to the ground to pass another car when i press gas pedal it take 2-4 seconds to response
I changed air filter, engine oil and transmission oil
and the problem still is there some steps to fix this problem.
Info : my friend has the same car and he doesn't have this problem.

And this pic for under hood parts:
I believe it is intentional, to relieve the gearbox from sudden torque increases and smoothen the drive. The auto gearbox is adaptive and "adjusts to your driving style" - though I never understood what the heck they mean by that. If I drive aggressively, will the transmission gradually become more aggressive? If I mostly trundle along highways, will it become more reluctant to gear down? What is the point of that? Would it not be better if it operated according to input every gear change?
So it could be the case that a reset of your computer may fix things. There are instructions on this board on how to do that, I never bothered myself.
I don't know if there is anything particularly wrong with your car, but I have that engine in mine too, and there is definitely a delay. Very noticeably from idle when I start from a standstill, even more so as you describe - when I slow down at an intersection and then floor it when a gap in the flow allows. Like the car gets stupidly surprised - "What? You want to accelerate? But you were braking just now!" and have to think a bit about what gear to use and how much to open the throttle and stuff.
It is not as severe as in some other cars I have driven, but decidedly more than in my former two supercharged Mercs, that would just dash off so abruptly that the tires squealed - and I can't remember it ever happening in my naturally aspired cars of old where the gas pedal directly actuated the throttle vanes - so I think the problem is compounded with the fact that the turbo needs a moment to spool up before full torque is achieved. The latter would also be the reason why it is much less noticeable higher up in the rpm register, because then the turbo needs much less time to get going.
2-4 sec to respond from fully stop is def not normal and has high safety concern.
Which is your situation tho? Need to be more precise on your wording so we can debug it
