bike will not idle

2004 busa:

Just installed a full yosh pipe, pc3r , removed pair valve, install blockoffs and did the small airbox mod.

The bike will not idle - runs really rough. Have tried several maps with the same results.

If I disconnect the connector (the black one) from the back of the airbox the idle smooths out , bike runs good - but I get an FI light.

Airbox - I removed the flapper, sealed the actuator hole and plugged hole from pair valve hose.

Put caps on the number 4 and number 1 vacuum lines.

I am going crazy here - any ideas?

I think I found the problem....there is a vacuum line that hooks to the IAP sensor (black connector on the back of the airbox). Just need to figure out where that vaccum line went...i pulled the airbox 2 days ago and forgot what it connects to....
