Need help pls

I’m just in need of some quick help since my tuner isn’t available at the moment, but my car starts to sputter only under 100% throttle and I can’t seem to figure out the issue why I’ve checked all of my vacuum lines checked for leaks my inlet and Mass airflow sensor are fine. I just want another opinion on what it could be or help narrow down what is the cause? For some reason, he also disengaged my warning lights to the check engine signal so I have zero clue on what it could be until either a buddy of mine or him can go in and unlock it all🤦🏽‍♂️ so I’m free balling at the moment🥲🥲 Mods: Aem short ram intake Process west top mount Perrin Catless up pipe Rsr Catless downpipe Grim speed electric boost controller Stock bpv Invidia n1 street exhaust (don’t think it’s necessary to list but lol)
