My new impact power plenum's power wheel is different from my older impact power wheel function. In older impact Max > 5 > a > 4 > b and so on...5 used to give slightly more fps than a. In newer impact 5 = a and 4 = b ... 5 equals a in fps . I have measured with caliber to make sure and they are the same measurements in numbers and letters.
Do they really change the function and why?
Or am I just imagining things
