Default What should an A4 H/C LS1 Idle at?

Just as the title states, Im curious on what an A4 H/C LS1 should idle at. My 1998 is supposedly set at 925 RPM, but is shows about 1000 on the tac

Thanks

That's a slightly "bigger" cam than I've got, but my setup idles
fine at 750RPM and I don't think you should need more than
800. But getting happy at 750 did take me a fair bit of time.

In any case the data value is to be believed and the tach is
"for amusement only".
