I like it tuned. I installed the switch a week ago. Been running around with it since. Nostly up and down the interstate and back roads. Towed a little (150 miles) this weekend. I gotta say....I like it in a tune better. Felt like it shifted too much for my liking using the switch. Had it go from 5th TCL to 4th TCL back to 5th no TCL in fairly quick order and regularly. That was without T/H on. With it on can't say it was much different than tuned. Anyways.....silver lining....I got options I guess.
