FRPP 65mm Throttle Body

I just installed it last night. I fired up the car and I noticed that when I step on the gas pedal and release it the rpms are slow to drop off. When they do they tend to come down to about 1200 for a few seconds then they drop off to normal. What gives, do I need to adjust the TPS & IAC?

theres a little screw under a rubber cap on the right side of the TB, try turning that all the way down (i had the same problem and thats how i fixed it, only i have a BBK)

some people back it out about 1/2 turn but i left mine all the way shut. dont know exactly what the difference is
