The "flutter" I guess is just a non rythmic sound when I let off the accelerator and the torque converter is not locked up. It is more like it is trying to come down to a smooth idle and eventually does. The more I drive it the less I notice it. I love the 80dd out on the freeway.
One other thing I have noticed is that in stock the torque conveter will lock at about 35 or so going uphill if the overdrive is locked out, but in the other tunes it will not do this. What points do you command the torque conveter to lock up in your tunes?
