I did not notice any increase in power no matter what anyone says. I bought it to change my tire size but speedo is still off. I called Diabolo and cs told me that you have to work on finding the sweet spot until the speedo is correct and tires are different size by different manufactures. I have a 35" tire and now have it programmed at a 33.5" tire to get my speedo closer. For trucks I was also told that you just program height of tire and forget about rim size & width. Very disappointed.
