Do you want to change it just at idle or everywhere?

Just idle, I have it where I want it everywhere else. But it idles so much better when cold, but the A/F leans out as it warms up and then the pcm keeps it at 14. something.

Set tps vs WOT cold table around idle RPM to 0.

More accurate but harder way would be to adjust the Fuel Air Multiplier table, that's the way I would do it but you shouldn't be having idle issues anyway with that cam.
