Re: Smart Tabs SX
As TD said, it will depend on your setup. I mounted mine but left the actuators out to take my test runs. I used GPS so I could get good data. I then followed the directions and started at hole 3 and made a run and I lost about 2.2MPH so I moved to #2 and gained that back, plus about 2.4 MPH. I never tried hole #1 as I am happy with #2.
