Revs not falling fast??

i was driving the car around for a spin and noticed the revs arent falling fast enough. i still have the stock flywheel and pressure plate along with an upgraded 2100 clutch. im wondering if it has to do so with my tranny. the engine is all good, just wondering which clutch kit you guys go with. thanks!

You mean you take it up to say ie: 6,000 rpm and it slowly falls ? could be a vacuum or IAC problem.

I could be wrong but good luck.
