Weird down rev problem

ok so i just got my tII swap into my gtu finished and now i'm doing last minute tuning and body work, but at the same time, i have a weird problem i can't figure out, the car when it is decellerating, it makes a weird bogging noise and revs down very slowly, even when i and just sitting still revving it up and letting it idle down, it idles down slowly and makes a weird bogging type noise... anyone out there with some opinions let me know

Backfiring is a sign of rich mixture, adjust your TPS maybe.
