What's interesting is that I had a service appointment today so removed it out of an abundance of caution. Wow the difference was night and day, I really felt the performance degrade. Needless to say I reinstalled this afternoon.
Moral of the story it just plain works😀
Nice, I love that feeling of you don't remember what you are missing until it's gone. I had a similar experience today with spacers. I removed mine two months ago and got them back on today. There are varying options on whether spacers impact handling, but let me tell you, the minute I got in the car I could feel the difference.

On my Dinan tune, I had it installed maybe a month after I bought the car and I really didn't drive it that much before I got it tuned, so I never really had a great comparison. I don't remove it for the dealer either. It has never been removed. But I do have a jumper plug on the unit that I can remove to go back to stock. I think I will pull it one of these days.
