Bill is right about the standard 3-way, and Keith is right about about the switch on my Spoiler.
The standard 2-way is 0-8, and I fully agree that's a bit strong. The 3 and 6 positions really do make a difference from the 8, as well as between themselves.
Now on my 88 Spoiler it was a fairly simple mod, but like Mica mentioned on that earlier thread it's probably not as simple on a Distillate.
