No, the sound is not there on the stock tune. And I did drive home from work this morning (about 20 miles) with the Level 1 tranny tune and no sound or vibration there either. I guess I will wait on the custom 87 performance tune and see what happens. Do you think the truck will eventually get used to the new ratio and "overcome" this sound and vibration the longer I drive with the 87 tow? Or should I just stick with the level 1 until I get the custom tune? Thanks for the help.
