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?

The fluttering is probably the ICP stablizing as you're decelerating and it causes a little rolling or flutter in the engine RPM which changes its tone. This wouldn't be a big issue to correct.

On your particular files, the converter strategy is left stock so it should be locking at the same point it was before. The only major shifting differences are in the 2-3 and 3-4 upshifts, with minor changes in 1-2, 2-1, 3-2, and 4-3 shifts, and they shouldn't be enough to affect the converter strategy.

One thing that might be happening is that because your power output for a given throttle curve has changed, it can have some moderate affects on the shifting because you are using less pedal to make the same power. Since all the major shifts are handled via MPH and Accelerator Position, this can change when and how the shifts occur. I suspect this is probably what you're experiencing.

I hope this helps.
