Slow throttle response Options

[kufor]

i'm new in here, so first of all "Hello everybody."

i just bought celica ST202 3S-GE (170hp) few weeks ago
on monday the first service visit has been completed:
change of timing belt, oil, oil filter, fuel filter, air filter and spark plugs also (NGK)
coolant has been checked and refilled, brake fluid too

unfortunately something got wrong, because the response to throttle is kind of slow comparing to what it was before the servicing
ECU reset didn't help

does anybody know what might be the issue please?
...or at least what to check before driving to toyota dealer?

what pipe do you mean mate?
pls mark with red circle
it has only one airbox and one resonator as far as i know

well, there's some work to do in the interior like fixing the center console, it is squeaking; mount a radio properly including wiring the cable straight from the battery and switch for power antenna; check the left rear panel, it's making some noises too; repair the passenger's safety belt, the spring seems to be broken and the whole belt is just laying on the floor
afterwards, i will measure the engine power output, because it looks like i'm missing some horses
when all of this will be finished, the time for power increase will come
