I have it. I had one on my 21, and it pulled a bit more, but it squealed. I just put one on in combination with my ARH headers and S&B intake, and it made a noticeable difference with that combo. I have not had it on long enough yet or been tearing around in dusty/desert to see if it will squeal again. It would be hard for me to take off until I tune and change the top pulley, which I'm going to wait to do.Anyone here in CO running an incognito pulley without a tune? How is it?
