I haven't been able to find one on my Mustang since my last search, a few months back.

My technique to find it was monitor fuel use (easier with OBDii), and drive as fast I can before it starts plummeting. 54-59 is all the same, then it starts dropping off. So 59 MPH is the ideal speed for me, pre current underbody/diffuser build.
