Exclamation Idling problems after mods . Help please

I have a 2000 3.8L v6 and just did some mods to it here that ar
Mac H-pipe Dual Exhaust
DynoMax Muffler
207*/215*, .493"/.495" lift cam
510 Lift Conical Springs
P & P heads and mil .030th
p & p upper and lower intakes
cold air intake

The car idles funny like it's hunting . it also sounds like it's missing . The throttle response is excellent and it drives fine and deffinitely has more power , but when you stop it almost stalls and starts hunting for an idle again . My question is , is there something we have wrong , or is this too much modifications for the computer to handle . Like we need a chip tune ? any help would me nice

with a different cam, you'll definitely need a dynotune.

For a quick fix, take it to a dealership and have them raise your idle.

Raising the idle speed is a very temporary fix. The problem is that the computer can't compensate for the greater airflow your engine is now capable of, you will need a MAF and computer reflash to get the engine to idle correctly. You could also have a vacuum leak.

HAdn't thought of the vacuum leak.

That could be. But you definitely need a dyno tune/reflash.
