Since you have headers now, you need a tune anyway. I assume you flashed your PCM to let it relearn itself also. A4 or M6 and what year?

look into a unmetered air leak...somewhere you might have pulled a vaccum line or not tightend something, a tune wouldnt hurt but thats probably not the reason why its got a high idle...

Its a 2001 m6. the only vacume line i disconnected was the little one that went into the T hose things for the air system. But after disconnecting it i plugged it.

I agree with a vacuum leak. Look around and see if anything is disconnected.
