did you change the tuning to raise the idle speed to 1000? If no, you have too much air getting in. Try closing your TB Blade idle set screw by 1 full turn.

don't know what diablo tuner you talking about, but the predator does not work on the 1998 cars.

do you have it on a scanner to know its really 1000, and not 800

my car registers 1100 on the dash tach,but is really 800 on the computer/aftermarket tach

one cheap way is to find somebody with HPtuners
I have a 1998 license, but your a little far of a drive away

Leave it alone. My 98 M6 always said it was running at 1000 rpm. It lies. Your gauge is off by 150-200 rpms all the way through the range. I have been watching mine. The stock idle setting is 800 rpms on the 98s, and I don't recommend going any lower than that.
