Loved it on my 95, not so much on Brenda's 96 as it made it shift at 4k WOT. But it was her car, and she didn't go WOT much. My 95 still shifts at 5200 WOT.
I don't think I am going to do it on my 97. Don't want to have to buy a tune to restore a 5000-5200 shift point. Some of us have a stock car otherwise, and don't need a tune.
