Idle rpm dump

I have had idle issues since owning my car. By that I mean when I release the throttle in low rpm's it will decided to drop anywhere from stalled out to 300revs. I have no boost leaks and my car runs fine besides that. I read about first gen ets intakes for 8's having issues and I have ordered the new one. I also have the following mods.

crower 272's
ets 2.5 ic core with all hard piping
walbaro 255
full 3in exhaust

My next guess would be the iacv if the new intake doesn't do anything?

is the car tuned?

if you don't know or aren't sure...cams can effect idle

as well as the intake

you can also try cleaning your maf sensor and while doing that make sure your maf screen is still fully intact

It is tuned, my tuner was surprised by the idle drop and indicated that it might be the iacv.
I will try cleaning the maf and see if that does anything.

I don't want to be too early in saying that the ets updated intake fixed the issue but I sure as heck drove better during my test drive. The true test will be traffic tomorrow.
