I run a 6R80 in my 98 Cobra using the Quick 6 controller. I didn't need to make any adjustments for idle after the install. The car stalled a few times while coming to a stop, but after driving it around a bit it's all but corrected itself.
that is good to know.
I have a Quick 4, but when I had the A9L on this new build (no specific auto tune) the car would die when putting it into gear.
Hopefully all goes well after I get the base idle set.
