Couple questions, Kev. I have a SCT3 tuner Is the IACDC what I am looking at in the data log? Also, is this something I can change myself or am I going to need to get with my tuner to change these settings?

What is your idle at with your Dragon TB?

That is correct. But you will have to get with your tuner to make these adjustments. I don't believe it can be adjusted with the handheld under options. Ideally you want the DC to be a little higher so that the IAC valve can control the air for idle. The throttle stop also MUST rest on the adjuster screw. If it does not come all the way back to the stop it will always be in a different spot and the computer will not know what "Closed TB" is supposed to be.
Also you need to datalog your Idle air integrator. It can be adjusted until it is as close to 0 as possible. (This is done through the tune as well)
The other thing with some SB TB's is that the blade sometimes contacts the housing and can cause it to bind before reaching the stop. This must be addressed before doing any of the setting procedures.
Thank you very much Kevin! Gonna shoot Greg an email and see when I get get in! :beer: The screw is set correctly, and the blade is slightly open to prevent the bind.

Good deal. As long as the blade opens and closes freely with the car off you should be OK.
The settings for the IAC need to be adjusted. Also, if you experience the RPM's drop either too fast or too slow when driving, then the Dashpot needs to be addressed as well.
Sometimes settings are closer on some cars than others. All are different though.
whats the best supplier to purchase this throttle body from?
This guy has one :beer:

This is exactly correct and to confirm what Kevin is saying I sealed up my whipple mono blade with some of my kids play-doh to confirm without a doubt it was air leaking by the blade that was causing the high idle.
Once that was confirmed I moved on to all the usual steps and for me I had to adjust the idle air integrator in the tune as well as remove some timing at idle and now my car idles correctly.

Nice!!! Thanks for your post Malcolm! Waiting to hear from my tuner!:beer:
x2, I have a Billetflow as well but I followed this to a T and my car runs dead nuts perfect at 800. No surging or fluxuation at all. I as well just let the car idle for about 10 plus minutes without touching the throttle once after I made the adjustment.
checked everything today, found out my TPS voltage was .985 Not bad, but not ideal. Slotted the TPS more and got it down to .96 and adjusted it according to billetflow's directions. We'll see....already back to where I was before and I've only driven it once since reset. For some reason, I'm not hearing from my tuner 
That will be my last step hopefully.....

Tune should get you fixed up bud
It's all in the tune. My Dragon idles rock solid stock (750-800). Even after WOT shutdown, cold, hot, etc. it's perfect. Got the Posi going on soon, hopefully my new tune will be as good as current with 60's, bap, mafia, blower, etc.
This is the type of stuff that makes a tuner or a "tooner" ..........
