I pulled my hood to paint the underside and installed the Dragon TB/Plenum I just picked up in the marketplace.

Got it installed and the TPS set, she still idles at 11-1200rpm. I've ordered a Ballenger AFR500v2 Wideband and new X4 so I can have Kevin Dunn/ @04sleeper tune it. He's been great on past Terminators. Hoping he can work his magic on this one too and get the tune back to 850-900rpm.

I'm honestly a bit worried, there is a LOT of air flowing around this throttle blade. I pulled the blade to clean it up, it doesn't appear modified. The last owner blocked off the IAC, guess they didn't need it.

It's been a while since I tuned my idle for the dragon, as I recall a very slight tip in with the throttle screw was necessary. Maybe a dime's width space or less. It at least has to touch. Also remember that it can take a bit for your ICU to learn. Give it a few miles as set.
If the blade doesn't rest on the stop screw, the blade will never stop in the same spot and your idle will be all over the place.
An IAC of .98v is the typical set point but I may have pushed mine a bit lower to .96v or so. I'll try and take a look with my Aeroforce gauge on that later. I'm idling at 800-850rpm.
You can find the IAC adjustment guide I used attached below (shamelessly ripped from SVTP).
