Default dipping idle after ls6 intake install

Just finished an LS6 intake install on my buddie's 2000 camaro.

Its seems to run fine. But after he revs it the idle dips down to about 300 or so then back up to 5-600 then idles fine.

wtf mate? Did we miss something?

Check your vacuum hoses on the rear of the intake.

Do you hear any leakage at all? Take a garden hose or something, put one end to your ear, walk the other end around the intake and listen for a leak. Also double check your torque on the 10 intake bolts, 89 in/lbs.

I have the same problem with mine once its been in storage for a while, it cranks up but wont stay running until it gets up to temp, and the idle drops all the time.
