UTCIS idle issues

I've gotten rid of megasquirt and return the car to stock to fine my WUR was bad (wouldn't adjust) and decide to order a UTCIS. Hooked it up and the car back fires out of the exhaust on start up but then idle goes to 3800-4k and stays there. Idle screw does nothing. Am I looking at a huge vacuum leak. Will be hooking the lap top tomorrow to check everything. other than a vacuum leak, what could it be.

Ones that have this, where are you connecting the vacuum to on the throttle body?
