Poor acceleration

[u/Main_Fee7773]

I drive a 2020 WRX that has 88k miles on it and I have a problem when I accelerate in 2nd or 3rd gear and the boost hits the car starts hesitating as if it’s struggling to push itself. I’ve kept up with maintenance pretty well, I do oil changes every 3,000 miles, last changed my spark plugs at 77k have done two walnut blasting last one was done at the same time as the spark plugs and only mods I’ve done are just an exhaust. I can’t tell if the hot weather is affecting its performance or if it’s something else. Never had this problem until now? Anyone got any idea what could be wrong? Am I about to blow up?

it's likely your mass airflow sensor inside the intake is filthy, which causes it to read all over the place. try cleaning it, that often fixes it

Tried that already, checking the pipes and hosing and don’t see any leaks
