Engine Hesitant for a split second! Whats that sound like?

[Kdubslugga]

If i give it gas it hesitates for a split second, the rpms drop about 100 to 200 rpm before climbing.. What does that sound like to you guys?? Not enough fuel or air or both, im stumped.

is that giving it gas just driving normally or flooring it ? mine was doing that a little when i first got it but only when i'd mash the gas........i adjusted the tps sensor and messed idle and advanced the timing a little and that helped.

do you hear a big whoosh of air coming from the intake? my daily driver does that big time along with cutting out and other shete

could be a vac leak or maybe your TPS or bypass valve
