After installing a bbk 62mm throttle body, bbk cai, and brenspeed tune, every time i rev up my rpm seems to stick and not come down as rapid as it should. Has anyone had that problem?

Go back to the stock TB. You're not gaining anything with the BBK plus they're known for causing issues. It's just not worth the aggravation unless you're FI or heavily modded internally. You can probably get it straightened out but for what? You'll see zero gain for your trouble.

The "dashpot" portion of your tune needs to adjusted or just get rid of the throttle body.
