Just seeing if anyone knows what could be it only happens at higher rpms and hitting the gas pretty hard

You’ve got a pretty vague description of what you're hearing.

What engine?
What mods?
Where’s the noise coming from (engine, exhaust)?

Judging by the little you described, it might be detonation (bad).

Cleaned the maf with electrical spray? Had some K&N oil on my SR maf and did the same thing. Cleaned and no more pops at high rpm/hard accel.
